[ Upstream commit 643d213a9a ]
Currently if the cm_id is not bound to any netdevice, than for such cm_id,
net namespace is ignored; which is incorrect.
Regardless of cm_id bound to a netdevice or not, net namespace must
match. When a cm_id is bound to a netdevice, in such case net namespace
and netdevice both must match.
Fixes: 4c21b5bcef ("IB/cma: Add net_dev and private data checks to RDMA CM")
