This reduces the latency of pinning framebuffers by
re-using the previous mapping, if available.

Additionally, DPT is preallocated when creating the FB, instead
of performing a bo allocation on every pin.

Remove the safety check in the first patch again, I didn't realize it was
needed even without the initial FB GGTT pinning removal.
