wifi: rt2x00: correct wrong BBP register in RxDCOC calibration 

[ Upstream commit 50da74e1e8b682853d1e07fc8bbe3a0774ae5e09 ]

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.
