ocfs2: fix possible use-after-free with AIO

commit 9b171e0c74ca0549d0610990a862dd895870f04a 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.
