[PATCH v2 7/3] xfs/194: unmount forced v4 fs during cleanup

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

From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Unmount the V4 filesystem we forcibly created to run this test during
test cleanup so that the post-test wrapup checks won't try to remount
the filesystem with different MOUNT_OPTIONS (specifically, the ones
that get screened out by _force_xfsv4_mount_options) and fail.
