Richard W.M. Jones a2f468e48f curl: Don't deref NULL pointer in call to aio_poll. 
In commit 63f0f45f2e the following
mechanical change was made:

         if (!state) {
-            qemu_aio_wait();
+            aio_poll(state->s->aio_context, true);
         }

The new code now checks if state is NULL and then dereferences it
('state->s') which is obviously incorrect.

This commit replaces state->s->aio_context with
bdrv_get_aio_context(bs), fixing this problem.  The two other hunks
are concerned with getting the BlockDriverState pointer bs to where it
is needed.

The original bug causes a segfault when using libguestfs to access a
VMware vCenter Server and doing any kind of complex read-heavy
operations.  With this commit the segfault goes away.
