ext4: Fix deadlock during directory rename
[ Upstream commit 3c92792da8506a295afb6d032b4476e46f979725 ]
As lockdep properly warns, we should not be locking i_rwsem while having
transactions started as the proper lock ordering used by all directory
handling operations is i_rwsem -> transaction start. Fix the lock
ordering by moving the locking of the directory earlier in
ext4_rename().
