Subject: macsec: ensure rx_sa is set when validation is disabled

From: Beniamino Galvani <bgalvani@redhat.com>

[ Upstream commit e3a3b626010a14fe067f163c2c43409d5afcd2a9 ]

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.
