Christoph Hellwig discovered that the kernel crashed trying to free the refcount btree per-ag reservation on a ro mount (because we don't create the reservation except for rw mounts and ro->rw remounts). So, test this to make sure we never do that again. :) Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>

# Mount a reflink/rmap filesystem ro (so the per-AG reservation isn't

# created) and unmount, to ensure that we free correctly.
