s4-drs: spelling fix, and simpler search expression

uSNChanged>=N is good enough, and offers a possibility of a simple
optimisation where the partition module could look for that expression
and check the partitions sequence number, then avoid searching a
partition that doesn't have any records with a larger uSN.
