drm/nouveau: factor out r535_gsp_msgq_peek()

Browse source

To receive a GSP message queue element from the GSP status queue, the
driver needs to make sure there are available elements in the queue.

The previous r535_gsp_msgq_wait() consists of three functions, which is
a little too complicated for a single function:
- wait for an available element.
- peek the message element header in the queue.
- recevice the element from the queue.

Factor out r535_gsp_msgq_peek() and divide the functions in
r535_gsp_msgq_wait() into three functions.

No functional change is intended.
