Fix perf probe to show which probe point is not found. With out this patch, it shows just "No probe point found." This doesn't help users if they specify several probes. e.g. # perf probe -f --add schedule --add test Fatal: No probe point found. This patch makes error message more helpful as below. # perf probe --add schedule --add test Fatal: Probe point 'test' not found. - probe not added.
