[PATCH 0/1] MR8472: wined3d: Fix double-free when shader_set_function fails.

[Yuxuan Shui (＠yshui)]

shader_set_function is inconsistent in whether it will cleanup the shader
before returning an error. Most of the callers of shader_set_function will do
the cleanup, which could double-free; but not all of them do, which means there
are also potential leaks. So make sure all callers do, and remove shader_cleanup
calls from shader_set_function.
