[PATCH] powerpc/kvm: Fix objtool warning for unannotated intra-function call in booke.o

[Sathvika Vasireddy]

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

Fix this warning by allowing the function to set the value of 'nip' field
using _THIS_IP_ macro, without having to use an additional assembly
instruction to save the instruction pointer.
