tracing: Fix wrong return in kprobe_event_gen_test.c

Browse Source 
Overwriting the error code with the deletion result may cause the
function to return 0 despite encountering an error. Commit b111545d26
("tracing: Remove the useless value assignment in
test_create_synth_event()") solves a similar issue by
returning the original error code, so this patch does the same.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
