network/route-metric: manage uint32_t RTAX_XYZ attributes in the same way

Browse Source 
Except for RTAX_CC_ALGO, all RTAX_XYZ attributes take uint32_t and
the kernel's default value is zero. So, let's unify handling of the
attributes.

This should not change any effective behavior. Just refactoring.
