[PATCH] tracing/kprobes: remove unnecessary checking of, trace_probe_is_enabled

["zhangwei(Jovi)" <jovi.zhangwei@huawei.com>]

Since tp->flags assignment was moved into function enable_trace_probe,
so there have no need to use trace_probe_is_enabled to check flags
in same function.

Remove the unnecessary checking.
