scsi: lpfc: Fix handling of fully recovered fabric node in dev_loss callbk

Browse source

In rare cases when a fabric node is recovered after a link bounce and
before dev_loss_tmo callbk is reached, the driver may leave the fabric node
in an inconsistent state with the NLP_IN_DEV_LOSS flag perpetually set.

In lpfc_dev_loss_tmo_callbk, a check is added for a recovered fabric node.
If the node is recovered, then don't queue the lpfc_dev_loss_tmo_handler
work. In lpfc_dev_loss_tmo_handler, the path taken for the recovered fabric
nodes is updated to clear the NLP_IN_DEV_LOSS flag.
