rbd: use BlockDriverState's AioContext
Drop the assumption that we're using the main AioContext. Convert
qemu_bh_new() to aio_bh_new() and qemu_aio_wait() to aio_poll().
The .bdrv_detach_aio_context() and .bdrv_attach_aio_context() interfaces
are not needed since no fd handlers, timers, or BHs stay registered when
requests have been drained.
