RDMA/uverbs: Check CAP_NET_RAW in user namespace for RAW QP create
[ Upstream commit a6dca091ba7646ff5304af660c94fa51b6696476 ]
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.
