Subject: flash_blk/eth.scr: fix check_configblock

The config block check aka check_configblock may fail during update
depending on the size of the hardware area boot partition which may
lead to the config block not getting properly migrated or updated if
still using parts of the legacy update procedure. This patch fixes
this by iterating over various sizes.
