Masami Hiramatsu (Google) 30c8fd31c5 tracing/kprobes: Fix to free objects when failed to copy a symbol
In __trace_kprobe_create(), if something fails it must goto error block
to free objects. But when strdup() a symbol, it returns without that.
Fix it to goto the error block to free objects correctly.
