scsi: lpfc: Fix -EOVERFLOW behavior for NVMET and defer_rcv
The driver is all set to handle the defer_rcv api for the nvmet_fc
transport, yet didn't properly recognize the return status when the
defer_rcv occurred. The driver treated it simply as an error and aborted
the io. Several residual issues occurred at that point.
Finish the defer_rcv support: recognize the return status when the io
request is being handled in a deferred style. This stops the rogue
aborts; Replenish the async cmd rcv buffer in the deferred receive if
needed.
