Basically BdrvPollCo->bs is only used by bdrv_poll_co(), and the
functions that it uses are both using bdrv_get_aio_context, that
defaults to qemu_get_aio_context() if bs is NULL.
Therefore pass NULL to BdrvPollCo to automatically generate a function
that create and runs a coroutine in the main loop.
