b43: LP-PHY: Fix a few typos in the RC calibration code
The RC calibration code has some typos - fix them. Also, make the default channel 7, as channel 1 is still broken (only channels 7 and 8, and occasionally 9 work). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
