[PATCH] powerpc/kvm/booke: fix altivec related build break

[laurentiu.tudor at nxp.com]

From: Laurentiu Tudor <laurentiu.tudor at nxp.com>

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'

Fixes: 09f984961c137c4b ("KVM: PPC: Book3S: Add MMIO emulation for VMX instructions")
