b43: HT-PHY: move TX fix to the separated function
On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix function which iterates over available cores. It matches our HT-PHY code which means it's probably also some TX fix. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
