Anton Gusev 089d656992 tracing: Fix wrong return in kprobe_event_gen_test.c 
[ Upstream commit bc4f359b3b607daac0290d0038561237a86b38cb ]

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.
