[PATCH] drm/amdgpu: fix error return code in mes_v12_1_map_test_bo

[Yang Wang]

The function mes_v12_1_map_test_bo incorrectly returned 0 unconditionallyon 
error path,
which would hide the real error code and mislead upperlayers about the failure 
status.
Fix it by returning the correct error code 'r' instead of 0.
