time: ntp: fix bug in ntp_update_offset() & do_adjtimex(), fix

The time_status conditional was accidentally placed right after we clear
the checked time_status bits, which causes us to take the conditional
every time through. This fixes it by moving the conditional to before we
clear the time_status bits.
