qla2xxx-32gbit: Fix device staying in blocked state

Browse Source 
From: Quinn Tran <qtran@marvell.com>

This patch fixes issue reported by some of the customers,
who discovered that after cable pull scenario the devices
disappear and path seems to remain in blocked state. Once
the device reappears, driver does not seem to update path
to online. This issue appears because of the defer flag
creating race condition where the same session reappears.
This patch fixes this issue by indicating SCSI-ML of device
lost when qlt_free_session_done() is called from qlt_unreg_sess().

Fixes: "qla2xxx: Improve RSCN handling in driver"
