tracing: Fix some alloc_event_probe() error handling bugs
There are two bugs in this code. First, if the kzalloc() fails it leads
to a NULL dereference of "ep" on the next line. Second, if the
alloc_event_probe() function returns an error then it leads to an
error pointer dereference in the caller.
