KVM: SEV: Don't WARN() if RMP lookup fails when invalidating gmem pages
The hook only handles cleanup work specific to SNP, e.g. RMP table
entries and flushing caches for encrypted guest memory. When run on a
non-SNP-enabled host (currently only possible using
KVM_X86_SW_PROTECTED_VM, e.g. via KVM selftests), the callback is a noop
and will WARN due to the RMP table not being present. It's actually
expected in this case that the RMP table wouldn't be present and that
the hook should be a noop, so drop the WARN_ONCE().
