[PATCH] dma-fence: Fix dma_fence_timeline_name() to call get_timeline_name()

[Baineng Shou]

dma_fence_timeline_name() incorrectly invokes ops->get_driver_name()
instead of ops->get_timeline_name(), so every caller receives the
driver name where the timeline name was expected.

This is a copy-paste regression that has resurfaced twice. It was
originally introduced by commit 62918542b7bf ("dma-fence: Fix sparse
warnings due __rcu annotations") when adding the __rcu casts, fixed
by commit 033559473dd3 ("dma-fence: Fix safe access wrapper to call
timeline name method"), and then accidentally reintroduced by commit
e58b4dea9054 ("dma-buf/dma-fence: Add dma_fence_test_signaled_flag()")
when both wrappers were refactored to use the new helper.
