[PATCH] iommufd/selftest: Iterate idev_ids in mock_domain's alloc_hwpt test

[Nicolin Chen]

The point in iterating variant->mock_domains is to test the idev_ids[0]
and idev_ids[1]. So use it instead of keeping testing idev_ids[0] only.

Jason/Kevin, I formated the patch with "-U4" so it shows the "for" line.
I didn't send it as a bug fix since it doesn't feel so critical that it
should bother stable trees -- yet if there's a need, I'd resend. Thanks!
