KVM: VMX: handle PML full VMEXIT that occurs during event delivery
[ Upstream commit b244c9fc251e14a083a1cbf04bef10bd99303a76 ]
With PML enabled, guest will shut down if a PML full VMEXIT occurs during
event delivery. According to Intel SDM 27.2.3, PML full VMEXIT can occur when
event is being delivered through IDT, so KVM should not exit to user space
with error. Instead, it should let EXIT_REASON_PML_FULL go through and the
event will be re-injected on the next VMENTRY.
