KVM: x86: Set guest's fixed-1 DR6 bits when delivering #DB payload
When delivering a #DB payload, set all DR6 bits that are fixed-1 from the
guest's perspective, not just the host's perspective. Don't WARN on a
"bad" payload (or existing DR6) even though KVM itself shouldn't set DR6
or synthesize a payload without the fixed-1 bits set, as userspace can
provide a completely arbitrary payload via KVM_SET_VCPU_EVENTS (and
"hardening" that flow is not worth the effort as there's no benefit in
practice).
