Louis Scalbert a90d4c45db isisd: fix metric calculation of classic lfa backup prefixes 
The isis-lfa-topo1 topotest shows backup routes with lower metrics than
the primary ones.

Backup routes metrics are incorrect because they only take into account
the path metric but not the prefix metric.

Add the prefix metric to the path metric on backup routes.

After the patch with a prefix metric of 10:
