[openib-general] [PATCH] RDMA/iwcm: Rewrite comment for iwcm_deref_id() to match code.

[Krishna Kumar]

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).
