Arnaldo Carvalho de Melo f4e2d182d6 perf probe: Avoid calling freeing routine multiple times for same pointer ...

[ Upstream commit d95daf5acc ]

When perf_add_probe_events() we call cleanup_perf_probe_events() for the
pev pointer it receives, then, as part of handling this failure the main
'perf probe' goes on and calls cleanup_params() and that will again call
cleanup_perf_probe_events()for the same pointer, so just set nevents to
zero when handling the failure of perf_add_probe_events() to avoid the
double free.
