RDMA/uverbs: Check CAP_NET_RAW in user namespace for QP create
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")
