ath9k: fix key allocation error handling for powersave keys
If no keycache slots are available, ath_key_config can return -ENOSPC.
If the key index is not checked for errors, it can lead to logspam that
looks like this: "ath: wiphy0: keyreset: keycache entry 228 out of range"
This can cause follow-up errors if the invalid keycache index gets
used for tx.
