If the port state is blocked and the fast io fail tmo has
fired then this patch will fail bsg requests immediately.
This is needed if userspace is sending IOs to test the transport
like with fcping, so it will not have to wait for the dev loss tmo.
With this patch he bsg req fast io fail code behaves like the normal
and sg io/passthrough fast io fail.
