drm/radeon: allow MIP_ADDRESS=0 for MSAA textures on Evergreen
MIP_ADDRESS should point to the resolved FMASK for an MSAA texture.
Setting MIP_ADDRESS to 0 means the FMASK pointer is invalid (the GPU
won't read the memory then).
The userspace has to set MIP_ADDRESS to 0 and *not* emit any relocation
for it.
