Observing lpfc port down after issuing hbacmd reset command
Failure in posting SGL buffers. If there is only one SGL buffer
and rrq is valid for its XRI, we are rightly returning NULL but
not adding the buffer back to the SGL list. So, number of buffers
become less than total count and repost fails during reset.
Add SGL buffer back to list before returning NULL.
