wifi: rt2x00: correct wrong BBP register in RxDCOC calibration

[ Upstream commit 50da74e ] Refer to Mediatek vendor driver RxDCOC_Calibration() function, when performing gainfreeze calibration, we should write register 140 instead of 141. This fix can reduce the total calibration time from 6 seconds to 1 second.
