ath9k: Fix regression in PA calibration
The commit "ath9k: Fix bugs in programming registers during PA CAL" removed a REG_READ of 0x7834. This resulted in incorrect computation of the subsequent value to be written in RF2G6. This patch fixes the regression by re-adding the REG_READ. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
