Madhavan Srinivasan 2ca13a4cc5 powerpc/perf: Use regs->nip when SIAR is zero 
In power10 DD1, there is an issue where the SIAR (Sampled Instruction
Address Register) is not latching to the sampled address during random
sampling. This results in value of 0s in the SIAR. Add a check to use
regs->nip when SIAR is zero.
