FW: Fix Menu Overflow Disable Option

The three button Menu Overflow would display no matter what setting was seleted within ROMControl, this commit makes a slight change to correctly return a result that reflects the users selection through ROMControl.

I had to enable then disable the option for it to function correctly (no reboot required), screenshot is below showing the absence of the overflow menu:

FW: Menu Overflow Disable - Different Implementation

Original method I used to enable the menu overflow disable option incorrectly disabled the menu overflow altogether for some devices due to a late night derp.

This implementation of the check to confirm if the menu overflow has been disabled through ROMControl should hopefully correct this issue.
