block/linux-aio: fix memory and fd leak

Browse source 
Hot unplugging -drive aio=native,file=test.img,format=raw images leaves
the Linux AIO event notifier and struct qemu_laio_state allocated.
Luckily nothing will use the event notifier after the BlockDriverState
has been closed so the handler function is never called.

It's still worth fixing this resource leak.
