RDMA/iwcm: Fix comment for iwcm_deref_id() to match code
In iwcm_deref_id(), the comment says : "If the last reference is being removed and iw_destroy_cm_id is waiting, wake up the waiting thread". The second part of the comment, "and iw_destroy_cm_id is waiting," is wrong, since this function either wakes the waiter already waiting in iwcm_deref_id, or enables it (so that when wait_for_completion() is performed later, it will immediately return).
