ENGR00290635-2 IPUv3 stripe:Fix a build warning

This patch fixes the following build warning by
initializing some local variables:
drivers/mxc/ipu3/ipu_calc_stripes_sizes.c: In function ‘ipu_calc_stripes_sizes’:
drivers/mxc/ipu3/ipu_calc_stripes_sizes.c:393:3: warning: ‘difwr’ may be used uninitialized in this function [-Wuninitialized]
drivers/mxc/ipu3/ipu_calc_stripes_sizes.c:393:3: warning: ‘onw’ may be used uninitialized in this function [-Wuninitialized]
drivers/mxc/ipu3/ipu_calc_stripes_sizes.c:393:3: warning: ‘inw’ may be used uninitialized in this function [-Wuninitialized]
