Dmitry Osipenko d3292daee3 dma-buf: Make locking consistent in dma_buf_detach() ...

The dma_buf_detach() locks attach->dmabuf->resv and then unlocks
dmabuf->resv, which could be a two different locks from a static
code checker perspective. In particular this triggers Smatch to
report the "double unlock" error. Make the locking pointers consistent.
