[PULL v2 02/15] block/aio_task: assert `max_busy_tasks` is greater than 0

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

From: Stefano Garzarella <sgarzare@redhat.com>

All code in block/aio_task.c expects `max_busy_tasks` to always
be greater than 0.

Assert this condition during the AioTaskPool creation where
`max_busy_tasks` is set.
