timekeeping: Don't stop time readers across hard_pps() update

hard_pps() update does not modify anything which might be required by time
readers so forcing readers out of the way during the update is a pointless
exercise.

The interaction with adjtimex() and timekeeper updates which call into the
NTP code is properly serialized by timekeeper_lock.
