[PATCH 20/44] KVM: MIPS: Setup VZ emulation? directly from kvm_mips_init()

Invoke kvm_mips_emulation_init() directly from kvm_mips_init() instead
of bouncing through kvm_init()=>kvm_arch_init().  Functionally, this is
a glorified nop as invoking kvm_arch_init() is the very first action
performed by kvm_init().

Emptying kvm_arch_init() will allow dropping the hook entirely once all
architecture implementations are nops.

No functional change intended.
