clock: Calculate frequency offset even without any delay estimation.

Browse Source 
If the "free_running" option is set, the "no adjust" calculates and
prints an estimation of the phase and frequency offsets to the remote
master.  Because the phase estimate requires a delay measurement, this
calculation is not performed without having the delay estimate first.
However, a typical transparent clock application will want to use the
frequency offset to correct the residence times to match the master's
frequency.

This patch adds a call to the "no adjust" routine even if no valid
delay measurement has been made.
