hw/intc/arm_gicv3_cpuif: Don't recalculate maintenance irq unnecessarily 

The maintenance interrupt state depends only on:
 * ICH_HCR_EL2
 * ICH_LR<n>_EL2
 * ICH_VMCR_EL2 fields VENG0 and VENG1

Now we have a separate function that updates only the vIRQ and vFIQ
lines, use that in places that only change state that affects vIRQ
and vFIQ but not the maintenance interrupt.
