tracing/kprobes: Fix field creation's bad error handling
When we define the common event fields in kprobe, we invert the error handling and return immediately in case of success. Then we omit to define specific kprobes fields (ip and nargs), and specific kretprobes fields (func, ret_ip, nargs). And we only define them when we fail to create common fields. The most visible consequence is that we can't create filter for k(ret)probes specific fields. This patch re-invert the success/error handling to fix it.
