fs: Fix possible use-after-free with AIO
commit 54c807e71d5ac59dee56c685f2b66e27cd54c475 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.
