block: Emulate bdrv_ioctl with bdrv_aio_ioctl and track both
Currently all drivers that support .bdrv_aio_ioctl also implement
.bdrv_ioctl redundantly. To track ioctl requests in block layer it is
easier if we unify the two paths, because we'll need to run it in a
coroutine, as required by tracked_request_begin. While we're at it, use
.bdrv_aio_ioctl plus aio_poll() to emulate bdrv_ioctl().
