[PATCH 4/3] generic/506: mount scratch fs before testing for prjquota presence

["Darrick J. Wong" <darrick.wong@oracle.com>]

From: Darrick J. Wong <darrick.wong@oracle.com>

On XFS, the _require_prjquota helper takes a path to a block device,
but (unintuitively) requires the block device to be mounted for the
detection to work properly.  Fix the detection code in generic/506.
