wifi: iwlwifi: add a compile time check for too long hcmds

Browse source

A host command that is bigger than the allowed payload length should be
sent with the NOCOPY flag. If it is sent without, we will get a warning.

We do know at compile time what is the maximum size of a hcmd payload that
the transport supports, so in order to catch bugs early,
add a compile time check to iwl_*_send_cmd_pdu to catch that.
