[PATCH v4 05/11] block-coroutine-wrapper.py: default to main loop aiocontext if function does not have a BlockDriverState parameter |

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.
