[media] vb2: Fix dma_dir setting for dma-contig mem type
The last argument of vb2_dc_get_user_pages() is of type enum
dma_data_direction, but the caller, vb2_dc_get_userptr() passes a value
which is the result of comparison dma_dir == DMA_FROM_DEVICE. This results
in the write parameter to get_user_pages() being zero in all cases, i.e.
that the caller has no intent to write there.
This was broken by patch "vb2: replace 'write' by 'dma_dir'".
