Subject: [PATCH 34/55] input: touchscreen: sur40: Stop abusing of min_buffers_needed field

'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
sur40 touchscreen 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.
