[media] vb2: Fix allocation size of dma_parms
When allocating memory to hold the device dma parameters in
vb2_dma_contig_set_max_seg_size(), the requested size is by mistake only
the size of a pointer. Request the correct size instead.
Fixes: 3f0339691896 ("media: vb2-dma-contig: add helper for setting dma max seg size")
