dm-raid: fix a race condition in request handling
raid_map calls pers->make_request, which missed the suspend check. Fix it with the new md_handle_request API. Fix: cc27b0c78c79(md: fix deadlock between mddev_suspend() and md_write_start()) Cc: Heinz Mauelshagen <heinzm@redhat.com> Cc: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org Reviewed-by: NeilBrown <neilb@suse.com> Signed-off-by: Shaohua Li <shli@fb.com>
