[PATCH 2/2] xfs/65[56]: don't unset SCRATCH_RTDEV here

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Both of these tests claim that they have to unset SCRATCH_RTDEV to avoid
formatting failures due to the rt bitmap consuming all the space in the
"small" data device.  However, the format doesn't constrain the size of
the data device, so the justification doesn't apply.  Remove the whole
thing.
