Commit c545781e1c55 ("dma-buf: doc polish for pin/unpin") disagrees with
the introduction of dynamism in commit: bb42df4662a4 ("dma-buf: add
dynamic DMA-buf handling v15") resulting in warning spew on
importing dma-buf. Silence the warning from the latter by only pinning
the attachment if the attachment rather than the dmabuf is to be
dynamic.
