tracing/kprobes: Skip symbol counting logic for module symbols in create_local_trace_kprobe()

commit b022f0c7e404 ("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")
avoids checking number_of_same_symbols() for module symbol in
__trace_kprobe_create(), but create_local_trace_kprobe() should avoid this
check too. Doing this check leads to ENOENT for module_name:symbol_name
constructions passed over perf_event_open.

No bug in newer kernels as it was fixed more generally by
commit 9d8616034f16 ("tracing/kprobes: Add symbol counting check when module loads")
