mlxsw: Set flood bridge type for FIDs

In the unified bridge model, the bridge type FID attribute is no longer
configured by the firmware, but instead by software when creating and
editing a FID via SFMR register.

Set this field as part of FID creation and edition flow. Default to 0
(reserved) as long as the driver operates in the legacy bridge model.
