[ Upstream commit 19597cad64d608aa8ac2f8aef50a50187a565223 ] 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.
