dma-buf: fix stale @lock references in struct dma_buf documentation
The kernel-doc comments for vmapping_counter and vmap_ptr in struct
dma_buf reference "@lock" as the protecting lock, but struct dma_buf
no longer has a "lock" member. The mutex was removed in favor of using
the dma_resv lock exclusively. The implementation correctly uses
dma_resv_assert_held(dmabuf->resv) in dma_buf_vmap() and
dma_buf_vunmap(), so update the documentation to reference @resv
instead.
