powerpc/kvm/booke: Fix altivec related build break

Add missing "altivec unavailable" interrupt injection helper
thus fixing the linker error below:

  arch/powerpc/kvm/emulate_loadstore.o: In function `kvmppc_check_altivec_disabled':
  arch/powerpc/kvm/emulate_loadstore.c: undefined reference to `.kvmppc_core_queue_vec_unavail'
