[PATCH rdma-next 1/6] RDMA/cma: Use the net namespace of the rdma_cm_id

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Parav Pandit <parav-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The net namespace is set during create_rdma_id(), while
the cma_resolve_iboe_route() used init namespace.

The original code was added in commit fa20105e09e9 ("IB/cma: Add support
for network namespaces"), but this path wasn't in use back then.

This patch updates the code to use right namespace, as a preparation
to the following patches.
