    gss_krb5: Fix the error handling path for crypto_sync_skcipher_setkey
    
    [ Upstream commit a3123341dc358952ce2bf8067fbdfb7eaadf71bb ]
    
    If we fail to call crypto_sync_skcipher_setkey, we should free the
    memory allocation for cipher, replace err_return with err_free_cipher
    to free the memory of cipher.
