IB/core: Namespace is mandatory input for address resolution

Browse Source 
In function addr_resolve() the namespace is a required input parameter
and not an output. It is passed later for searching the routing table
and device addresses. Also, it shouldn't be copied back to the caller.

Fixes: 565edd1d55 ('IB/addr: Pass network namespace as a parameter')
