KVM: VMX: Don't freeze guest when event delivery causes an APIC-access exit
commit 99b82a1437cb31340dbb2c437a2923b9814a7b15 upstream.
According to SDM 27.2.4, Event delivery causes an APIC-access VM exit.
Don't report internal error and freeze guest when event delivery causes
an APIC-access exit, it is handleable and the event will be re-injected
during the next vmentry.
