restore initial power sweep behaviour

Browse Source 
if user define a delta_p that is reduced because of saturation,
then this initial setting is still kept for power sweep to be sure
that the full amplitude of sweep is used.

SI power = 0 dBm
max power amp1 = 20 dBm,
user_defined_delta_p set by user = 3
80 channels, so pch_max = 20 - 10log10(80) = 0.96 dBm
power_sweep -> power range [-3, 0] dBm

then for initial design,
   pref = 0 dBm
   computed_delta_p =
      min(pch_max, pref + user_defined_delta_p) - pref = 0.96

but for -3 power sweep
   pref = -3 dBm
   computed_delta_p =
      min(pch_max, pref + user_defined_delta_p) - pref =
      min(0.96,    -3 + 3) - (-3) = 3
   so the user defined delta_p is applied as much as possible
