drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()
This ensures that the memory mapped by ioremap for adev->rmmio, is
properly handled in amdgpu_device_init(). If the function exits early
due to an error, the memory is unmapped. If the function completes
successfully, the memory remains mapped.
