aio: io_getevents() should return if io_destroy() is invoked

This patch wakes up a thread waiting in io_getevents if another thread
destroys the context.  This was tested using a small program that spawns a
thread to wait in io_getevents while the parent thread destroys the io context
and then waits for the getevents thread to exit.  Without this patch, the
program hangs indefinitely.  With the patch, the program exits as expected.
