media: staging: rkisp1: rsz: set default format if the given format is not RKISP1_ISP_SD_SRC

When setting the sink format of the 'rkisp1_resizer'
the format should be supported by 'rkisp1_isp' on
the video source pad. This patch checks this condition
and sets the format to default if the condition is false.
