fix breakage in do_rmdir()
syzbot reported and bisected a use-after-free due to the recent init
cleanups.
The putname() should happen only after we'd *not* branched to retry,
same as it's done in do_unlinkat().
Reported-by: syzbot+bbeb1c88016c7db4aa24@syzkaller.appspotmail.com
Fixes: e24ab0ef689d "fs: push the getname from do_rmdir into the callers"
