drm/vmwgfx: Use a per-device semaphore for reservation protection
Don't use a per-master semaphore (ttm lock) for reservation protection, but
rather a per-device semaphore. This is needed since clients connecting using
render nodes aren't master aware.
The ttm lock used should probably be replaced with a reader-write semaphore
once the function down_xx_interruptible() is available.
