wr-servo: move generation of the state name earlier

Since commit f3d427ee

, we lost the concept of "next_state" (to make code
simple), but this means that we should report to wr_mon the state string
we acted on, not the next. Otherwise, we see SYNC_PHASE all the time,
when we are actually waiting for SYNC_SEC or SYNC_NSEC to complete the
adjustment.
