[PATCH v2 27/36] media: sunxi: sun8i-di: Fix misuse of min_buffers_needed field

[Benjamin Gaignard]

'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
sun8i-di driver doesn't use DMA engine and just want to specify
the minimum number of buffers to allocate when calling VIDIOC_REQBUFS.
That 'min_reqbufs_allocation' field purpose so use it.
V4L2 framework doesn't allow to allocated less than 1 buffer.
Setting min_buffers_need to 1 is useless so remove it.
