Before commit "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping"
there was a need to ensure that there were sufficient buffers supplied from
the user to cover those being sent to the VPU (always 1).

Now the buffers are linked 1:1 between MMAL and V4L2,
therefore there is no need for that check, and indeed it is wrong
as there is no need to submit all the buffers before starting streaming.
