gpu-compute: Ignore GPU kernel names
gpu-compute: Ignore GPU kernel names

ROCm 4 seems to have updated the akc, and the only real issue that has
occured is that we're no longer able to read kernel names in the same
way as we were in ROCm 1.6. This patch removes the prior method of
reading kernel names and gives all kernels a temporary name
