mlxsw: spectrum: Add mlxsw_sp_fid_ops.fdb_clear_offload
If there are any offloaded FDB entries at bridge master of an NVE device at the time that it's un-offloaded, their offloaded marks need to be cleared. How that is done depends on whether the bridge in question is vlan aware. Therefore add a per-FID-type operation. Implement the operation for the 802.1q and 802.1d bridges. Add and publish a function mlxsw_sp_fid_fdb_clear_offload() to dispatch to the new operation according to FID type.
