fix qemu_aio_flush
qemu_aio_wait by invoking the bh or one of the aio completion
callbacks, could end up submitting new pending aio, breaking the
invariant that qemu_aio_flush returns only when no pending aio is
outstanding (possibly a problem for migration as such).
(cherry picked from commit 986c28d655dc9196c9c426c667c1764bd3d6d5bd)
