Fix/zgersum gpu

These modifications fix the GPU side of the sum reduction tasks for StarPU.

I am not sure why the codelet_zgersum.c file is completed "added" in the change so I'm submitting this MR as a draft.

@AntJego The problem is that your branch was not base on the latest master. I did a rebase of the branch, so please correctly fetch (not pull) the branch before applying the modifications that I will request on the code. Thanks.
