Add missing parameter documentation for virtio_dma_buf_attach()
function to fix kernel-doc warnings:

Warning: drivers/virtio/virtio_dma_buf.c:41 function parameter 'dma_buf' not described in 'virtio_dma_buf_attach'
Warning: drivers/virtio/virtio_dma_buf.c:41 function parameter 'attach' not described in 'virtio_dma_buf_attach'

The function documentation was missing descriptions for both the
'dma_buf' and 'attach' parameters. Add proper parameter documentation
following kernel-doc format.

Seems to be a subset of:
[PATCH v2] virtio: Update kerneldoc in drivers/virtio/virtio_dma_buf.c
