drm/amdgpu: Avoid possiblity of kernel crash in 'gmc_v8_0, gmc_v7_0_init_microcode()'

Browse source

If the function 'gmc_v8_0_ or gmc_v7_0_init_microcode()' fails, the
driver will just fail to load, hence return -EINVAL rather having BUG(),
fixes WARNING: Do not crash the kernel unless it is absolutely
unavoidable--use WARN_ON_ONCE() plus recovery code (if feasible) instead
of BUG() or variants
