Michel Dänzer ae1b1a4816 drm: radeon: fix up bus mastering when writeback is disabled 
When writeback isn't used, actually disable it in the hardware.

Not doing this might waste bus bandwidth or even cause memory corruption or
system crashes on systems that check bus transfers. No such incident has been
reported though.

* completed rendering.
*
* KW: It's also a good way to find free buffers quickly.
*
* KW: Ideally this loop wouldn't exist, and freelist_get wouldn't
* sleep. However, bugs in older versions of radeon_accel.c mean that
* we essentially have to do this, else old clients will break.
*
* However, it does leave open a potential deadlock where all the
* buffers are held by other clients, which can't release them because
* they can't get the lock.
