selftests: kvm/x86: Test the flags in MSR filtering and MSR exiting

Browse source

When using the flags in KVM_X86_SET_MSR_FILTER and
KVM_CAP_X86_USER_SPACE_MSR it is expected that an attempt to write to
any of the unused bits will fail.  Add testing to walk over every bit
in each of the flag fields in MSR filtering and MSR exiting to verify
that unused bits return and error and used bits, i.e. valid bits,
succeed.
