This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8.

spur_freq_sd (for self-corr in AGC) is defined with respect to the
center of each 20MHz channel while spur_phase_delta (for self-corr
in Rx and spur data filter) is defined with respect to the center
of current RF channel.

So in short, we need to subtract spur_freq_sd (for self-corr in AGC)
by the offset between the center of primary20 and the center of RF
channel in SW. This offset could be +/10 MHz for dynamic 40.

What actual bug is this causing?  Should this be applied to 3.4?

The original commmit is causing low rate's sensitivity degrade in ht40
mode. Will send v2 patch with updated commit log. And yes it should be
applied to 3.4.
