smb: smbdirect: introduce smbdirect_connection_recv_io_done()

Browse source

This is basically a copy of recv_done() in client and server,
with the following additions:

- Only handling the SMBDIRECT_EXPECT_DATA_TRANSFER code path,
  as we'll have separate functions for the negotiate messages.
- Using more helper variables
- Improved logging
- Add credits_requested == 0 error check
- Add data_offset not 8 bytes aligned error check
- Use disable_work(&sc->recv_io.posted.refill_work)
  before smbdirect_connection_put_recv_io, when it
  is followed by smbdirect_socket_schedule_cleanup()

This will be used on common between client and server in future
and replace the existing recv_done() functions.
