[AMDGPU] Avoid processing functions in amdgpu-propagate-attributes pass for shaders 

The pass amdgpu-propagate-attributes ("Early/Late propagate attributes
from kernels to functions") is currently run also for shaders, where
it does nothing. Modify the check so the pass only processes functions
for kernels.
