Subject: [PATCH] drbd: explicitly submit meta data requests with REQ_NOIDLE

For some reason we have assumed NOIDLE was implied
by one of the other flags we set. It is not (anymore?).
Explicitly set REQ_NOIDLE for synchronous meta data updates,
or we can seriously starve random writes when using CFQ.
