fs/direct-io.c: fix possible use-after-free with AIO
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.
