Since the kprobe-events selftest shows OK or NG with the reason, the
WARN_ON_ONCE()s for each place are redundant. Let's remove it.

Note, the ktests we run to validate commits, fail when it detects a WARN()
triggered.

If this fails in any configuration, ktest will not detect it failed.

Hmm, I think there are 2 options,
 - remove pr_warn() instead. (WARN_ON_ONCE + pr_warn is redundant)
 - Or, remove WARN_ON_ONCE() from each place, but add WARN_ON_ONCE() when
   `warn` is not zero.

Thank you,
