4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bill Kuzeja <William.Kuzeja@xxxxxxxxxxx>
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.
Fixes: 1535aa75a3d8 ("scsi: qla2xxx: fix invalid DMA access after command aborts in PCI device remove")
