[PATCH MANUALSEL 5.14 8/9] KVM: x86: nSVM: restore int_vector in svm_clear_vintr

[Sasha Levin]

From: Maxim Levitsky <mlevitsk@xxxxxxxxxx>

[ Upstream commit aee77e1169c1900fe4248dc186962e745b479d9e ]

In svm_clear_vintr we try to restore the virtual interrupt
injection that might be pending, but we fail to restore
the interrupt vector.
