hw/intc/arm_gicv3_kvm: Remove writes to ICPENDR registers
As per the arm-vgic-v3 kernel doc [1]:
Accesses to GICD_ICPENDR register region and GICR_ICPENDR0 registers
have RAZ/WI semantics, meaning that reads always return 0 and writes
are always ignored.
The state behind these registers (both 0 and 1 bits) is written by
writing to the GICD_ISPENDR and GICR_ISPENDR0 registers, unlike
some of the other set/clear register pairs.
Remove the useless writes to ICPENDR registers in kvm_arm_gicv3_put().
