RDMA/counter: Check CAP_NET_RAW check in user namespace for RDMA counters

Browse Source 
Currently, the capability check is done in the default
init_user_ns user namespace. When a process runs in a
non default user namespace, such check fails.

Since the RDMA device is a resource within a network namespace,
use the network namespace associated with the RDMA device to
determine its owning user namespace.
