ocfs2: fix the la space leak when unmounting an ocfs2 volume

This bug has existed since the initial OCFS2 code.  The code logic in
ocfs2_sync_local_to_main() is wrong, as it ignores the last contiguous
free bits, which causes an OCFS2 volume to lose the last free clusters of
LA window on each umount command.
