radv: fix HTILE metadata initialization in presence of subpass clears 

If the driver ends up by performing a slow depthstencil clear,
the HTILE metadata won't be initialized correctly.

This fixes random VM faults on Polaris while running CTS
with Bas's runner. This doesn't seem to regress performance.
