[openib-general] [PATCH] fix for a bug in cma_ib_listen()

[Steve Wise]

Fix for bug in cma_ib_listen().  

Set cm_id to NULL after destroying the listen ib_cm_id so rdma_destory_id() doesn't try and destroy it again later.

This fixes the crash I'm seeing when I destroy a cma_id after rdma_listen() fails...
