[PATCH] qla2xxx: Add missing ->vport_slock while calling qlt_update_vp_map

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

All other callers of qlt_update_vp_map() already hold ->vport_slock
while updating the vp target map, so go ahead and add the missing
->vport_slock within qla24xx_disable_vp() code.
