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 set the format to default if the condition is false.

Fixes: 56e3b29f9f6b "media: staging: rkisp1: add streaming paths"

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.
