[PATCH] IB: fix CM use-after-free

Browse source

If the CM REQ handling function gets to error2, then it frees
cm_id_priv->timewait_info.  But the next line goes through
ib_destroy_cm_id() -> ib_send_cm_rej() -> cm_reset_to_idle(),
which ends up calling cm_cleanup_timewait(), which dereferences the
pointer we just freed.  Make sure we clear cm_id_priv->timewait_info
after freeing it, so that doesn't happen.
