Hi!
Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid.
Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.
I don't think this fixes the bug... and thus we should not need it in stable.
Given that this goes together with an actually bug fix that was backported, it *is*, for once, actually useful to have it in stable.
