md/raid10: wait barrier before returning discard request with REQ_NOWAIT

Browse source

[ Upstream commit 3db4404435 ]

raid10_handle_discard should wait barrier before returning a discard bio
which has REQ_NOWAIT. And there is no need to print warning calltrace
if a discard bio has REQ_NOWAIT flag. Quality engineer usually checks
dmesg and reports error if dmesg has warning/error calltrace.
