KVM: arm/arm64: Get rid of its->initialized field
The its->initialized doesn't bring much to the table, and creates unnecessary ordering between setting the address and initializing it (which amounts to exactly nothing). Let's kill it altogether, making KVM_DEV_ARM_VGIC_CTRL_INIT the no-op it deserves to be.
