[PATCH] media: pxa_camera: declare variable when DEBUG is defined

[trix]

From: Tom Rix <t...@redhat.com>

When DEBUG is defined this error occurs

drivers/media/platform/pxa_camera.c:1410:7: error:
  ‘i’ undeclared (first use in this function)
  for (i = 0; i < vb->num_planes; i++)
       ^
The variable 'i' is missing, so declare it.

Fixes: 6f28435d1c15 ("[media] media: platform: pxa_camera: trivial move of 
functions")
