Chao Yu f4746f2d79 f2fs: get rid of online repaire on corrupted directory 
[ Upstream commit 884ee6dc85b959bc152f15bca80c30f06069e6c4 ]

syzbot reports a f2fs bug as below:

Online repaire on corrupted directory in f2fs_lookup() can generate
dirty data/meta while racing w/ readonly remount, it may leave dirty
inode after filesystem becomes readonly, however, checkpoint() will
skips flushing dirty inode in a state of readonly mode, result in
above panic.

Let's get rid of online repaire in f2fs_lookup(), and leave the work
to fsck.f2fs.
