[PATCH rdma-next v1 6/7] RDMA/counter: Check CAP_NET_RAW check in user namespace for RDMA counters

[Leon Romanovsky <leon@kernel.org>]

From: Parav Pandit <parav@nvidia.com>

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.

Fixes: 1bd8e0a9d0fd ("RDMA/counter: Allow manual mode configuration support")
