f2fs: find parent dentry correctly
If dotdot directory is corrupted, its slot may be ocupied by another file. In this case, dentry[1] is not the parent directory. Rename and cross-rename will update the inode in dentry[1] incorrectly. This patch finds dotdot dentry by name. Signed-off-by: Sheng Yong <shengyong1@huawei.com> [Jaegeuk Kim: remove wron bug_on] Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
