[U-Boot] [PATCH 3/5] smart-gateway-mt7688: Correct build time check for overwriting factory data

[Tom Rini]

The board file has a build time check to ensure that we do not have the
redundant environment overwriting the factory data.  However,
multiplying the redundant offset by two isn't correct.  Since we
correctly confirm that U-Boot itself will not go in to the primary
environment we only need to next make sure that the redundant
environment + the size of that does not exceed where the factory data
is.
