KVM: arm/arm64: vgic: Don't flush/sync without a working vgic
If the vgic hasn't been created and initialized, we shouldn't attempt to
look at its data structures or flush/sync anything to the GIC hardware.
This fixes an issue reported by Alexander Graf when using a userspace
irqchip.
Fixes: 0919e84c0fc1 ("KVM: arm/arm64: vgic-new: Add IRQ sync/flush framework")
