[SCSI] qla2xxx: Properly handle Vport state-change-notifications.
Drivers do SCRs for each Vport. When something changes in the
fabric, firmware generates one interrupt for each RSCN. Based on
the current implementation, in each case, we make recursive calls
to handle RSCN for physical and each subsequent virtual ports.
The fix is to also take into consideration the vp_idx, which is
set by the firmware to indicate the vport the RSCN was meant for.
