Steven Rostedt (Google) e36f19a645 ring-buffer: Reuse rb_watermark_hit() for the poll logic ...

The check for knowing if the poll should wait or not is basically the
exact same logic as rb_watermark_hit(). The only difference is that
rb_watermark_hit() also handles the !full case. But for the full case, the
logic is the same. Just call that instead of duplicating the code in
ring_buffer_poll_wait().
