[XFS] Disable queue flag test in barrier check.
md raid1 can pass down barriers, but does not set an ordered flag on the
queue, so xfs does not even attempt a barrier write, and will never use
barriers on these block devices.
Remove the flag check and just let the barrier write test determine
barrier support.
A possible risk here is that if something does not set an ordered flag and
also does not properly return an error on a barrier write... but if it's
any consolation jbd/ext3/reiserfs never test the flag, and don't even do a
test write, they just disable barriers the first time an actual journal
barrier write fails.
