ar71xx: Move OpenMesh image target validation into subfunction
The platform_check_image_openmesh function used break statements to signal that the board name matched the image target. This worked because the sysupgrade binary checked the image inside a loop. The break statement stopped the loop and skipped any additional check. Instead the check should be done without such sideeffects by simply combining the board names and image targets. Only a mismatch should cause a negative result for the caller and skipping of the additional checks. Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com>
