James.Smart@Emulex.Com ea84c3f74d [SCSI] lpfc driver 8.0.30 : dev_loss and nodev timeouts
Fix handling of the dev_loss and nodev timeouts.

Symptoms: when remote port disappears for a period of time longer then
either nodev_tmo or dev_loss_tmo, the lpfc driver worker thread will
stall removing that remote port.

Cause: removing remote port involves un-blocking and sync-ing
corresponding block device queue. But corresponding node in the lpfc
driver is still in the NPR(?node port recovery?) state and mid-layer
gets SCSI_MLQUEUE_HOST_BUSY as a return value when it is trying to call
queuecommand() with command for that node (AKA remote port)

Fix: Instead of returning SCSI_MLQUEUE_HOST_BUS from queuecommand() for
nodes in NPR states complete it with retry-able error code  DID_BUS_BUSY
