[why] These static variables saves the RLC Scratch registers address.
When we installed multiple GPUs (for example: XGMI setting) and
multiple GPUs call the function at same time. The RLC Scratch
registers address are changed each other. Then it caused
reading/writing to wrong GPU.
[fix] Removed the static from the variables. The variables are
in stack.
