net/mlx5e: MACsec, fix update Rx secure channel active field

The main functionality for this operation is to update the
active state of the Rx security channel (SC) if the new
active setting is different from the current active state
of this Rx SC, however the relevant active state check is
done post updating the current active state to match the
new active state, effectively blocks any offload state
update for the Rx SC in question.

Fix by delay the assignment to be post the relevant check.
