ath6kl: Don't advertise HT capability for incapable firmware
With firmwares which do not support rsn capability override
(ATH6KL_FW_CAPABILITY_RSN_CAP_OVERRIDE) from host would
cause 4-way handshake failure when HT cap is advertised.
To fix this, do not advertise HT cap with cfg80211 for
those fw.
kvalo: fix a checkpatch warning
