b8d71c09f31a9cae248d167dddc75c66d5135ff2 block: make bdrv_co_do_write_zeroes stricter in producing aligned requests
Right now, bdrv_co_do_write_zeroes will only try to align the
beginning of the request. However, it is simpler for many
formats to expect the block layer to separate both the head *and*
the tail. This makes sure that the format's bdrv_co_write_zeroes
function will be called with aligned sector_num and nb_sectors for
the bulk of the request.
