Christian König f45f57cce5 dma-buf: stop using the dmabuf->lock so much v2 ...

The attachment list is now protected by the dma_resv object.

Stop holding the dma_buf->lock while calling ->attach/->detach,
this allows for concurrent attach/detach operations.

v2: cleanup commit message and locking in _debug_show()
