RDMA/cm: Revert association of an RDMA device when binding to loopback
Revert the following change from commit 6f8372b6 ("RDMA/cm: fix
loopback address support")
The defined behavior of rdma_bind_addr is to associate an RDMA
device with an rdma_cm_id, as long as the user specified a non-
zero address. (ie they weren't just trying to reserve a port)
Currently, if the loopback address is passed to rdma_bind_addr,
no device is associated with the rdma_cm_id. Fix this.
It turns out that important apps such as Open MPI depend on
rdma_bind_addr() NOT associating any RDMA device when binding to a
loopback address. Open MPI is being updated to deal with this, but at
least until a new Open MPI release is available, maintain the previous
behavior: allow rdma_bind_addr() to succeed, but do not bind to a
device.
