[PATCH] perf: fix exit value of perf list

[Stephane Eranian]

This patch fixes an issue with the exit value of perf list:

$ perf list; echo $?
129

perf list returns an error exit code even though there is
no error.

There was a stray exit(129) in print_events(). This patch
removes this exit().

$ perf list; echo $?
0
