nouveau: fix elusive dma bug

In some situations WAIT_RING would get called while the GPU was processing
data from outside the "master" ring, which caused dma.free to be updated
incorrectly and much fun was had.

WAIT_RING will now wait until it reads GET values from within the main ring
buffer before calculating free space.
