I had similar problem when compiled this driver with:

-msoft-float

Got driver working only with -mhard-float and arm v7. Left a some info in README:

https://github.com/brektrou/rtl8821CU#arm-architecture-tweak-for-this-driver-this-solves-compilation-problem-of-this-driver

But you need to find out how to do this on arm v8 system.
