Subject: scsi: qla2xxx: Fix crash in qla2xxx_eh_abort on bad ptr
From: Bill Kuzeja <William.Kuzeja@stratus.com>
commit 5f7c2beef819d9ea2d1b814edf6f5981420e9cf8 upstream.
After a Qlogic card breaks when initializing (test case), the system can
crash in qla2xxx_eh_abort if processing anything but a scsi command type
srb.
