openocd: drop iteration downsampling for keep_alive()

Browse Source 
The function keep_alive() is optimized and return immediately if
has nothing to do.
There is no need to overly-complicate the code with extra counters
or time computation plus the relative checks to reduce the number
of calls to keep_alive().

Drop such extra code.
