lp: linearly recover dio_calls_period on missed dio calls

Browse source 
Increment dio_calls_period by one on each call where the diophantine
solver is not triggered (until it returns to the initial period),
gradually re-enabling dio solving after it was backed off, instead of
leaving the period at its doubled value indefinitely.
