commit bebb2a47 upstream.

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: 565edd1d ('IB/addr: Pass network namespace as a parameter')
