Oliver Upton 59e9cd63a5 KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF
[ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ]

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.
