If a buffer is backed by dmabuf, wait on its reservation object's exclusive
fence before flipping.
v2: First commit
v3: Remove object_name_lock acquire
v4: Move wait ahead of mark_page_flip_active
Use crtc->primary->fb to get GEM object instead of pending_flip_obj
use_mmio_flip() return true when exclusive fence is attached
Wait only on exclusive fences, interruptible with no timeout
v5: Move wait from do_mmio_flip to mmio_flip_work_func
Style tweaks to more closely match rest of file
v6: Change back to unintteruptible wait to match __i915_wait_request due to
inability to properly handle interrupted wait.
Warn on error code from waiting.
v7: No change
v8: Test for !reservation_object_signaled_rcu(test_all=FALSE) instead of
obj->base.dma_buf->resv->fence_excl
