Correctly reset the PAT9125 filament counters

Browse Source 
When the error count is cleared, the cumulative deltas as well as the
segment lenght which is kept inside the stepper isr need to be reset.

Introduce a helper function fsensor_reset_err_cnt to clear all the
required variables in one place which can be used in most cases
(the only exceptions being quality measument).

Introduce a new function st_reset_fsensor to also clear the segment
lenght within the isr.
