Ganesh Ajjanagadde 8a5b60a6b1 avutil/opencl_internal: add av_warn_unused_result 
clSetKernelArg can return an error due to lack of memory (for instance):
https://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clSetKernelArg.html.
Thus this error must be propagated.

Currently should not trigger warnings, but adds robustness.
Untested.
