Fix the menu render issue in Big Sur 11.0.1

The true explanation why the patch is working remains unknown yet, since 21 is a magical value in the dyld. The following is the logic why I try the number 0.

The original Big Sur use an statement: if somevalue <21, then do sth. Glitches are everywhere.
the current kext is patched to do the statement: if somevalue >=21, then do sth. The logic is illustrated here: https://osy.gitbook.io/hac-mini-guide/details/metal-driver-fix However it's working partially in big sur.
So I replace the value 21 to 0: if somevalue >=0, then do sth. And it's working now, with no side effect found yet.

BTW, since I suppose a value between 0 and 21 would be better, I tried with different numbers for HVK. The patch is working with the patch if somevalue >=19, but no with somevalue >=20. However, I think it's still better to use if somevalue >=0 if there's no obvious side effect.

I wonder the VRAM usage is about the same ? I didn't run any 3D APP, just chrome with youtube. that's it

This may be a system issue, not related to the patch.

For the record, I'm using the kext all the time. Before 20:19, the VRAM is 99% but I did nothing other than Chrome.

After 20:19, I reboot the device, and start playing StarCraft2 (with metal engine). The VRAM remains ~30%, but the GPU processor reaches 99%(which means the game uses a lot calculations)
