This patch fixes a bug that, when offset is provided but function is
lost, parse_perf_probe_point() will give a "" string as function name,
so the checking code at the end of parse_perf_probe_point() become
useless. For example:
# perf probe +0x1234
Failed to find symbol in kernel
Error: Failed to add events.
After this patch:
# perf probe +0x1234
Semantic error :Offset requires an entry function.
Error: Command Parse Error.
