net: macsec: Verify that send_sci is on when setting Tx sci explicitly
When setting Tx sci explicit, the Rx side is expected to use this
sci and not recalculate it from the packet.However, in case of Tx sci
is explicit and send_sci is off, the receiver is wrongly recalculate
the sci from the source MAC address which most likely be different
than the explicit sci.
Fix by preventing such configuration when macsec newlink is established
and return EINVAL error code on such cases.
