[PATCH rdma-next v2 4/9] RDMA/uverbs: Check CAP_NET_RAW in user namespace for QP create

[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. Due to this
when a process is running using Podman, it fails to create
the QP.

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: 2dee0e545894 ("IB/uverbs: Enable QP creation with a given source QP number")
