Roland Dreier 8294f29767 RDMA/nes: Get rid of ring_doorbell parameter of nes_post_cqp_request() 
Every caller of nes_post_cqp_request() passed it NES_CQP_REQUEST_RING_DOORBELL,
so just remove that parameter and always ring the doorbell.

Roland Dreier 1ff66e8c1f RDMA/nes: Encapsulate logic nes_put_cqp_request() 
The iw_nes driver repeats the logic

	if (atomic_dec_and_test(&cqp_request->refcount)) {
		if (cqp_request->dynamic) {
			kfree(cqp_request);
		} else {
			spin_lock_irqsave(&nesdev->cqp.lock, flags);
			list_add_tail(&cqp_request->list, &nesdev->cqp_avail_reqs);
			spin_unlock_irqrestore(&nesdev->cqp.lock, flags);
		}
	}

over and over.  Wrap this up in functions nes_free_cqp_request() and
nes_put_cqp_request() to simplify such code.

In addition to making the source smaller and more readable, this shrinks
the compiled code quite a bit:
