[media] v4l: omap3isp: Don't check for missing get_fmt op on remote subdev
The remote subdev of any video node in the OMAP3 ISP is an internal subdev that is guaranteed to implement get_fmt. Don't check the return value for -ENOIOCTLCMD, as this can't happen. While at it, move non-critical code out of the mutex-protected section.
