Bernard Metzler 33fb27fd54 RDMA/siw: Fix passive connection establishment 
Holding the rtnl_lock while iterating a devices interface address list
potentially causes deadlocks with the cma_netdev_callback. While this was
implemented to limit the scope of a wildcard listen to addresses of the
current device only, a better solution limits the scope of the socket to
the device. This completely avoiding locking, and also results in
significant code simplification.

Fixes: c421651fa2 ("RDMA/siw: Add missing rtnl_lock around access to ifa")
