Oliver Upton ceb720324e KVM: nVMX: Handle pending #DB when injecting INIT VM-exit 
commit 684c0422da upstream.

SDM 27.3.4 states that the 'pending debug exceptions' VMCS field will
be populated if a VM-exit caused by an INIT signal takes priority over a
debug-trap. Emulate this behavior when synthesizing an INIT signal
VM-exit into L1.
