[PATCH 2/2] KVM: SVM: Set NMI_VECTOR in event_inj in svm_inject_nmi()

[Jim Mattson <jmattson@google.com>]

Include NMI_VECTOR (2) in svm->vmcb->control.event_inj when injecting an
NMI in svm_inject_nmi(), matching vmx_inject_nmi().

Although hardware ignores EVENTINJ.VECTOR on VMRUN when TYPE is NMI (APM
Vol. 2, "Event Injection"), omitting NMI_VECTOR causes
svm_get_entry_info() to report vector 0 instead of 2 to the kvm_entry
tracepoint, and causes svm_cancel_injection() to copy an exit_int_info
value with vector 0 into the active VMCB.

Fixes: 95ba82731374 ("KVM: SVM: Add NMI injection support")
