After fixing the same issue in the set_caching IOCTL and Chris' request to check out the possibilities for an improved RPM ref handling I noticed that we have the same issue in the set_tiling IOCTL. Fix this up.I didn't see any bug reports about this one, but the GTT unbind operation on this path accesses the HW, which needs the ref.
