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

[ Upstream commit 449728196d65fce513dbacf4d3696764be1c6524 ]

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.
