Revert the approach for skipping lockstat_probe_func call when doing

lock_success/lock_failure, introduced in r228424, by directly skipping
in dtrace_probe.

This mainly helps in avoiding namespace pollution and thus lockstat.h
dependency by systm.h.

As an added bonus, this also helps in MFC case.
