ath9k: fix checks for first subframe delimiter padding
The commit "ath9k_hw: Fix exceed transmission burst-time of 5GHz" added a padding of 60 delimiters on the first subframe to work around an issue on AR9380, but it lacked the checks to prevent it from being applied to pre-AR9380, enterprise AR9380 or AR9580+ Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.
