ath9k_hw: remove pCap->keycache_size
Similar to the number of tx queue, the number of keycache entries depends on the chip and shouldn't be messed with based on EEPROM data. Remove this field and stick to using AR_KEYTABLE_SIZE Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
