ext4: fix possible use-after-free with AIO
commit 091e26dfc156aeb3b73bc5c5f277e433ad39331c upstream.
Running AIO is pinning inode in memory using file reference. Once AIO
is completed using aio_complete(), file reference is put and inode can
be freed from memory. So we have to be sure that calling aio_complete()
is the last thing we do with the inode.
