drm/amd: Drop error message about failing to load SDMA firmware

The error path for SDMA firmware loading is unnecessarily noisy.
When a firmware is missing 3 errors show up:
```
amdgpu 0000:07:00.0: Direct firmware load for amdgpu/green_sardine_sdma.bin failed with error -2
[drm:sdma_v4_0_early_init [amdgpu]] *ERROR* Failed to load sdma firmware!
[drm:amdgpu_device_init [amdgpu]] *ERROR* early_init of IP block <sdma_v4_0> failed -19
```

The error code for the device init is bubbled up already, remove the
second one.
