Subject: [PATCH v5 02/28] rdma/cm: Allow enabling reuseaddr in any state

From: Sean Hefty <sean.hefty@...el.com>

The rdma_cm only allows setting reuseaddr if the corresponding
rdma_cm_id is in the idle state.  Allow setting this value in
other states.  This brings the behavior more inline with
sockets.
