net/mlx5e: Update restore chain id for slow path packets

net/mlx5e: Update restore chain id for slow path packets

Currently encap slow path rules just forward to software without
setting the chain id miss register, so driver doesn't restore
the chain, and packets hitting this rule will restart from tc chain
0 instead of continuing to the chain the encap rule was on.

Fix this by setting the chain id miss register to the chain id mapping.
