When amdkfd and radeon are compiled inside the kernel image (not as modules),
radeon will load before amdkfd and will set *kfd2kgd to its interface
structure. Therefore, we must not set *kfd2kgd to NULL when amdkfd is loaded
because it will override radeon's initialization and cause kernel BUG.

This change does nothing, that is what the original code did already.
