KVM: x86: Set guest DR6 by kvm_queue_exception_p() in instruction emulation
Record DR6 in emulate_db() and use kvm_queue_exception_p() to set DR6
instead of directly using kvm_set_dr6() in emulation, i.e. rely on the
standard exception path to set DR6 via kvm_deliver_exception_payload().
This keeps the handling of DR6 during #DB injection consistent with other
code paths.
No functional change intended.
