Avi Kivity e8a48342e9 KVM: VMX: Conditionally reload debug register 6 
Only reload debug register 6 if we're running with the guest's
debug registers.  Saves around 150 cycles from the guest lightweight
exit path.

dr6 contains a couple of bits that are updated on #DB, so intercept
that unconditionally and update those bits then.
