KVM: VMX: Don't freeze guest when event delivery causes an APIC-access exit 

commit 99b82a1437 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.
