drs_utils: HWM in 'samba-tool drs replicate --local' always zero
The code to check for the 'repsFrom' highwatermark didn't have any
effect because the hwm variable was overwritten (initialized to all
zeroes) further down.
Using a zero HWM probably wouldn't have impacted functionality because
we were still correctly using the uptodatenessvector, which should
avoid a full replication.
This was introduced in commit
e2ba17d26af42974e5d, presumably by
accident.
