net/mlx5: SD, defer vport metadata init until SD is ready

Browse source

Allow SD devices to transition to switchdev before the SD group is
fully up. Metadata allocation requires the SD group to be ready, so
defer it from esw_offloads_enable() until SD shared-FDB activation.

Add mlx5_esw_offloads_init_deferred_metadata() which allocates per-vport
metadata and refreshes the ingress ACLs that were previously programmed
with metadata=0. The helper is idempotent and can be called multiple
times.
