If ocfs2_reserve_cluster_bitmap_bits() fails with ENOSPC, it will try to free truncate log and then retry. Since ocfs2_try_to_free_truncate_log will lock/unlock global bitmap inode, we have to unlock it before calling this function. But when retry reserve and it fails with no global bitmap inode lock taken, it will unlock again in error handling branch and BUG. This issue also exists if no need retry and then ocfs2_inode_lock fails. So fix it.
