Patch Review

**Status**: Good refactor.

Extracts the `f->ops == &pvr_queue_job_fence_ops` check into a new `pvr_queue_fence_is_ufo_backed()` (static, internal) helper, used in both `to_pvr_queue_job_fence()` and `pvr_queue_fence_is_native()`. The naming is clear and the doc comment is accurate.

Note: this reintroduces `pvr_queue_fence_is_ufo_backed` as a *static* function after patch 4 renamed the *exported* one. The static one checks if a raw `dma_fence` has the job fence ops (UFO-backed), while the exported `pvr_queue_fence_is_native()` checks if it's a scheduler fence from this driver. Different scopes, different purposes - no confusion.

**No issues.**
