I just re-verify it, applying your patch alone does not solve the problem.

The issue is with adhoc mode and when it first starts, there is
 no SSID to associate with if the SSID is an unique one. The patch
basically bypass the "sitesurvey" as it could never find another site
with the wanted SSID, so that's why adhoc didn't work before. It
worked if the module has some associations before starting adhoc mode
because now it won't do another sitesurvey. ... this is how I
interpreted the logic. I've been testing it for the past few hours and
wpa2, adhoc all works well with the r7812u driver now.

Thanks for your help. Will you send this to patch to Linus?
