Subject: [PATCH 3/3] scsi: qla2xxx: Remove incorrect trap
This BUG_ON() is triggered when there is no fc_port with a certain
loop ID in the scsi host vp_fcports list, but there is one in
lport_loopid_map. As these two data structures do not change
simultaneously and atomically, such a trap is invalid.
