PCI/P2PDMA: Update DMABUF lifecycle docs after move_notify() rename
Commit 95308225e5ba ("dma-buf: Rename dma_buf_move_notify() to
dma_buf_invalidate_mappings()") left the DMABUF section of the P2PDMA
documentation pointing at move_notify(), a symbol that no longer exists.
Readers grepping for it find nothing, and this is the only place in
Documentation/ describing the revocation requirement.
Name the current function and record that importers which cannot unmap
within bounded time have to be rejected at attach time, which is what makes
the synchronous unmap on remove() achievable.
Fixes: 95308225e5ba ("dma-buf: Rename dma_buf_move_notify() to dma_buf_invalidate_mappings()")
