perf events: Fix false positive build warning with older GCC's
gcc 4.2.1 produces:
util/probe-event.c: In function 'add_perf_probe_events':
util/probe-event.c:883: warning: 'tev' may be used uninitialized in this function
make: *** [util/probe-event.o] Error 1
Newer GCCs get this right.
To work it around, initialize the variable to NULL so that older GCCs see
it as initialized too.
