media: staging: media: zoran: fix usage of vb2_dma_contig_set_max_seg_size
[ Upstream commit 241f5b67fb48def58643f279dfb8468bdd54b443 ]
vb2_dma_contig_set_max_seg_size need to have a size in parameter and not
a DMA_BIT_MASK().
While fixing this issue, also fix error handling of all DMA size
setting.
