Marc Zyngier 8ca18eec2b KVM: arm/arm64: vgic: Don't notify EOI for non-SPIs 
When we inject a level triggerered interrupt (and unless it
is backed by the physical distributor - timer style), we request
a maintenance interrupt. Part of the processing for that interrupt
is to feed to the rest of KVM (and to the eventfd subsystem) the
information that the interrupt has been EOIed.

But that notification only makes sense for SPIs, and not PPIs
(such as the PMU interrupt). Skip over the notification if
the interrupt is not an SPI.
