Quinn Tran d03346d4ab scsi: qla2xxx: Fix system crash due to bad pointer access 
commit 19597cad64d608aa8ac2f8aef50a50187a565223 upstream.

User experiences system crash when running AER error injection.  The
perturbation causes the abort-all-I/O path to trigger. The driver assumes
all I/O on this path is FCP only. If there is both NVMe & FCP traffic, a
system crash happens. Add additional check to see if I/O is FCP or not
before access.
