[PATCH 5/5] media: davinci: vpif_capture: fix the check on suspend/resume callbacks

["Lad, Prabhakar" <prabhakar.csengg@gmail.com>]

It is possible to call STREAMON without having any buffers queued.
So vb2_is_streaming() can return true without start_streaming()
having been called. Only after at least one buffer has been
queued will start_streaming be called.

The check vb2_is_streaming() is incorrect as this would start
the DMA without having proper DMA pointers set up. this patch
uses vb2_start_streaming_called() instead to check is streaming
was called.
