mac80211: Fix misplaced return in AES-GMAC key setup
Commit 8ade538bf39b ("mac80111: Add BIP-GMAC-128 and BIP-GMAC-256
ciphers") had the success return in incorrect place before the
crypto_aead_setauthsize() call which practically ended up skipping that
call unconditionally.
The missing call did not actually change any functionality since
GMAC_MIC_LEN (16) is identical to the maxauthsize in gcm(aes) and as
such, the default value used for the authsize parameter.
