net/mlx5e: MACsec, fix Tx SA active field update

Browse source 
Currently during update Tx security association (SA) flow, the Tx SA
active state is updated only if the Tx SA in question is the same SA
that the MACsec interface is using for Tx,in consequence when the
MACsec interface chose to work with this Tx SA later, where this SA
for example should have been updated to active state and it was not,
the relevant Tx SA HW context won't be installed, hence the MACSec
flow won't be offloaded.

Fix by update Tx SA active state as part of update flow regardless
whether the SA in question is the same Tx SA used by the MACsec
interface.

Fixes: 8ff0ac5be1 ("net/mlx5: Add MACsec offload Tx command support")
