macsec: ensure rx_sa is set when validation is disabled
macsec_decrypt() is not called when validation is disabled and so
macsec_skb_cb(skb)->rx_sa is not set; but it is used later in
macsec_post_decrypt(), ensure that it's always initialized.
Fixes: c09440f7dcb3 ("macsec: introduce IEEE 802.1AE driver")
