net: marvell: prestera: fix uninitialized vid in prestera_port_vlans_add

prestera_bridge_port_vlan_add should have been called with vlan->vid,
however this was masked by the presence of the local vid variable and I
did not notice the build warning.

Fixes: b7a9e0da2d1c ("net: switchdev: remove vid_begin -> vid_end range from VLAN objects")
