KVM: x86: Prevent host from panicking on shared MSR writes.
commit 8b3c3104c3f4f706e99365c3e0d2aa61b95f969f upstream.
The previous patch blocked invalid writes directly when the MSR
is written. As a precaution, prevent future similar mistakes by
gracefulling handle GPs caused by writes to shared MSRs.
