drm/via: clean up reclaim_buffers
A few things
- kill reclaim_buffers, it's never ever called because via does not set
DRIVER_HAVE_DMA
- inline the idlelock dance into the buffer reclaim logic and make it
a simple preclose cleanup function
- directly call the the dma_quiescent function and kill the needless
if check.
v2: Actually drop the idlelock when we take it. Reported by James
Simmons.
v3: Rebased onto latest drm-next.
v4: Fixup the refactor.
v5: More fixup the refactor - I've accidentally changed the check for
any master to checking whether the closing fd is the master.
v6: Don't forget to drop the idlelock in the early return path, too.
