Making reclaim_buffers OS-independent

[Felix <fx...@gm...>]

Currenly in linux-core the driver callback reclaim_buffers is called
with a single argument "filp". In reclaim_buffers you need OS-specific
knowledge to extract the device pointer from the filp. In the BSD DRM
reclaim_buffers takes two arguments, "dev" and "filp". Could we change
the linux version to use the same API? This would allow implementing an
OS-agnostic reclaim_buffers function in a driver.
