[PATCH v4 2/3] powerpc/perf: Drop the case of returning 0 as instruction pointer

[Kajol Jain]

Drop the case of returning 0 as instruction pointer since kernel
never executes at 0 and userspace almost never does either.

Fixes: e6878835ac47 ("powerpc/perf: Sample only if SIAR-Valid
bit is set in P7+")
