Heming Zhao 7782e3b3b0 ocfs2: fix the space leak in LA when releasing LA ...

Commit 30dd3478c3 ("ocfs2: correctly use ocfs2_find_next_zero_bit()")
introduced an issue, the ocfs2_sync_local_to_main() ignores the last
contiguous free bits, which causes an OCFS2 volume to lose the last free
clusters of LA window during the release routine.

Please note, because commit dfe6c5692f ("ocfs2: fix the la space leak
when unmounting an ocfs2 volume") was reverted, this commit is a
replacement fix for commit dfe6c5692f.
