Marek Szyprowski d81e870d5a [media] v4l: vb2-dma-contig: fail if user ptr buffer is not correctly aligned ...

The DMA transfer must be aligned to a specific value. If userptr is not aligned
to DMA requirements then unexpected corruptions of the memory may occur before
or after a buffer.  To prevent such situations, all unligned userptr buffers
are rejected at VIDIOC_QBUF.
