scsi: storvsc: use default I/O timeout handler for FC devices
FC disks issue I/O directly to the host storage port driver, this is diffirent to VHD disks where I/O is virtualized and timeout is handled by the host VSP (Virtualization Service Provider). FC disks are usually setup in a multipath system, and they don't want to reset timer on I/O timeout. Timeout is detected by multipath as a good time to failover and recover.
