xfs: Fix possible use-after-free with AIO
commit 4b05d09c18d9aa62d2e7fb4b057f54e5a38963f5 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.
