hw/intc/arm_gicv3_cpuif(): Remove redundant tests of is_a64()

Browse source 
In the gicv3_{irq,fiq,irqfiq}_access() functions, in the
arm_current_el(env) == 3 case we do the following test:
    if (!is_a64(env) && !arm_is_el3_or_mon(env)) {
        r = CP_ACCESS_TRAP_EL3;
    }

In this check, the "!is_a64(env)" is redundant, because if
we are at EL3 and in AArch64 then arm_is_el3_or_mon() will
return true and we will skip the if() body anyway.

Remove the unnecessary tests.
