Without this, polling on the dma-buf (and presumably other devices
synchronizing against our rendering) would return immediately, even
while the BO was busy.

Before we can add vmap shrinking, we really need to know which vmap'ings
are currently being used. So switch to get/put interface. Stubbed put
fxns for now.

This was always the intention, but somehow it was never wired up
properly.

We need to return a new sgt, since the caller takes ownership of it.

Currently msm does not implement gem_prime_mmap. Without this it is not
possible to draw onto a dma-buf from userspace (making its very hard to
implement the Android rendering model).
Fixing this is just a matter of adding a little boilerplate.
