KVM: arm/arm64: vgic-new: Removel harmful BUG_ON
When changing the active bit from an MMIO trap, we decide to explode if the intid is that of a private interrupt. This flawed logic comes from the fact that we were assuming that kvm_vcpu_kick() as called by kvm_arm_halt_vcpu() would not return before the called vcpu responded, but this is not the case, so we need to perform this wait even for private interrupts. Dropping the BUG_ON seems like the right thing to do.
