drm/amdgpu/sdma6: Update SDMA 6.0.3 FW version to include UMQ protected-fence fix

On GFX11.0.3, earlier SDMA firmware versions issue the
PROTECTED_FENCE write from the user VMID (e.g. VMID 8) instead of
VMID 0. This causes a GPU VM protection fault when SDMA tries to
write the secure fence location, as seen in the UMQ SDMA test
(cs-sdma-with-IP-DMA-UMQ)

Fixes the below GPU page fault:
