Use a plain array for any group ID that's less than 64, and punt
anything beyond that to an xarray. 64 fits in a page even for 4KB
page sizes and with the planned additions.
This makes the expected group usage faster by avoiding a hash and lookup
to find our list, and it uses less memory upfront by not allocating any
memory for provided buffers unless it's actually being used.

The read/write opcodes use it already, but the recv/recvmsg do not. If
we switch them over and read and validate this at init time while we're
checking if the opcode supports it anyway, then we can do it in one spot
and we don't have to pass in a separate group ID for io_buffer_select().

In the tasklets (completer, responder, and requester) check the return
value from rxe_get() to detect failures to get a reference. This only
occurs if the qp has had its reference count drop to zero which indicates
that it no longer should be used.
The ref is never 0 today because the tasklets are flushed before the ref
is dropped. The next patch changes this so that the ref is dropped then
the tasklets are flushed.

The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit
54f586a915 ("rfkill: make new event layout opt-in") is unusable
since it is based on RFKILL_IOC_EXT_SIZE which has not been defined.
Fix that by replacing the undefined constant with the constant which

When doing simulate_fw_crash operation periodically with a short interval
time such as 10 seconds, it is easy happened WMI command timed out for
WMI_SCAN_CHAN_LIST_CMDID in ath11k_reg_update_chan_list().
log:
[42287.610053] ath11k_pci 0000:01:00.0: wmi command 12291 timeout
[42287.610064] ath11k_pci 0000:01:00.0: failed to send WMI_SCAN_CHAN_LIST cmd
[42287.610073] ath11k_pci 0000:01:00.0: failed to perform regd update : -11
Note that this issue does not occur with a longer interval such as 20 seconds.
The reason the issue occurs with a shorter interval is the following steps:
1) Upon initial boot, or after device recovery, the initial hw scan plus
the 11d scan will run, and when 6 GHz support is present, these scans
can take up to 12 seconds to complete, so ath11k_reg_update_chan_list()
is still waiting the completion of ar->completed_11d_scan.
2) If a simulate_fw_crash operation is received during this time, those
scans do not complete, and ath11k_core_pre_reconfigure_recovery()
complete the ar->completed_11d_scan, then ath11k_reg_update_chan_list()
wakeup and start to send WMI_SCAN_CHAN_LIST_CMDID, but firmware is crashed
at this moment, so wmi timed out occur.
To address this issue, reset the 11d state during device recovery so that
WMI_SCAN_CHAN_LIST_CMDID does not timed out for short interval time such
as 10 seconds.
