Revert "usb-storage: Drop useless null test in usb_msd_handle_data()"
This reverts commit a1cbfd554e11bb8af38c2f3e1f1574bf4c563cd2.
Test isn't useless. scsi_req_enqueue() may finish the request (will
actually happen for requests which don't trigger any I/O such as
INQUIRY), then call usb_msd_command_complete() which in turn will
set s->req to NULL after unref'ing it.
