When the 'kprobe_event=' kernel command-line parameter is not provided,
there is no need to execute setup_boot_kprobe_events().
This change optimizes the initialization function init_kprobe_trace()
by skipping unnecessary work and effectively prevents potential blocking
that could arise from contention on the event_mutex lock in subsequent
operations.
