Namhyung Kim 7949ba1fa2 perf probe: Propagate error code when write(2) failed
When it failed to write probe commands to the probe_event file in
debugfs, it needs to propagate the error code properly.  Current code
blindly uses the return value of the write(2) so it always uses
-1 (-EPERM) and it might confuse users.
