net: marvell: prestera: initialize err in prestera_port_sfp_bind

prestera_port_sfp_bind() returns err after walking the ports node. If no
child node matches the port's front-panel id, err is never assigned.

Initialize err to 0 because absence of a matching optional port device
tree node is not an error. In that case no phylink is created and port
creation should continue with port->phy_link left NULL. Errors from
malformed matched nodes and phylink_create() still propagate.
