drm/i915/dmabuf: Update dma_buf_ops.unmap_dma_buf callback to use drm_gem_unmap_dma_buf()

Browse Source 
The dma_buf_ops.unmap_dma_buf callback used in i915,
i915_gem_unmap_dma_buf(), has the same code as drm_gem_unmap_dma_buf().
In order to eliminate defining and using duplicate function, it updates
the dma_buf_ops.unmap_dma_buf callback to use drm_gem_unmap_dma_buf().
