[PATCH v3 3/3] scsi: qla2xxx: Remove incorrect trap

[Anastasia Kovaleva <a.kovaleva@yadro.com>]

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.
