Subject: [PATCH v2 1/6] KVM: x86: selftests: Fix typos in macro variable use

Without the leading underscore, these variables are referencing a
variable in the calling scope. It only worked before by accident
because all calling scopes had a variable with the right name.

Fixes: cd34fd8c758e ("KVM: selftests: Test PMC virtualization with forced emulation")
