dm: disable barriers
This patch causes device-mapper to reject any barrier requests. This is done
since most of the targets won't handle this correctly anyway. So until the
situation improves it is better to reject these requests at the first place.
Since barrier requests won't get to the targets, the checks there can be
removed.
