i2c: dev: Fix the race between the release of i2c_dev and cdev

I don't know whether it will apply cleanly to all of them; I can deal with those where it doesn't.

I applied it to 4.14, 4.19, 5.4, and 5.6. It does apply to 4.9 but as the patch it depends on is not there, I don't think it will help.

thanks,
