scsi: lpfc: Move NPIV's transport unregistration to after resource clean up

Browse source

[ Upstream commit 4ddf01f2f1 ]

There are cases after NPIV deletion where the fabric switch still believes
the NPIV is logged into the fabric.  This occurs when a vport is
unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the
fabric.

Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including
the fabric D_ID, removes the last ndlp reference and frees the ndlp rport
object.  This sometimes causes the race condition where the final DA_ID and
LOGO are skipped from being sent to the fabric switch.

Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID
and LOGO are sent.
