media: i2c: ov7670: 0 instead of -EINVAL was returned

Browse Source 
[ Upstream commit 6a4c664539e6de9b32b65ddcf767ec1bcc1d7f8a ]

If the media bus is unsupported, then return -EINVAL. Instead it
returned 'ret' which happened to be 0.

This fixes a smatch warning:

ov7670.c:1843 ov7670_parse_dt() warn: missing error code? 'ret'
