zebra: fix mpls setting at startup

When an interface is recovered, and has mpls in auto mode, the mpls value may be misconfigured. Fix this by checking if the interface is in automatic mode. If it is the case, pick up the 'mpls_dynamic' value to change the real mpls value. Signed-off-by: Philippe Guibert <[email protected]>
