aio: fix potential leak in aio_run_iocb().
commit 754320d6e166d3a12cb4810a452bde00afbd4e9a upstream.
iovec should be reclaimed whenever caller of rw_copy_check_uvector() returns,
but it doesn't hold when failure happens right after aio_setup_vectored_rw().
Fix that in a such way to avoid hairy goto.
