[PATCH] tracing/kprobes: Add missing check for skipping symbol counting logic

[Nikolay Kuratov]

In commit b022f0c7e404
("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")
it was already done for symbol in __trace_kprobe_create(), but func in
create_local_trace_kprobe() is also valid usage.
Not doing so leads to ENOENT for module_name:symbol_name
constructions passed over perf_event_open().

Fixes: b022f0c7e404 ("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")
