powerpc/kvm: Fix unannotated intra-function call warning 



objtool throws the following warning:
  arch/powerpc/kvm/booke.o: warning: objtool: kvmppc_fill_pt_regs+0x30:
  unannotated intra-function call

Fix the warning by setting the value of 'nip' using the _THIS_IP_ macro,
without using an assembly bl/mflr sequence to save the instruction
pointer.
