KVM: selftests: Verify KVM preserves userspace writes to "durable" MSRs
Assert that KVM provides "read what you wrote" semantics for all "durable"
MSRs (for lack of a better name). The extra coverage is cheap from a
runtime performance perspective, and verifying the behavior in the common
helper avoids gratuitous copy+paste in individual tests.
Note, this affects all tests that set MSRs from userspace!
