freedreno: fix sysmem rendering being used when clear is used

This batch->cleared value is only used to decide to use sysmem rendering
or not, so it should include any buffers that are affected by a clear.

This is required because the a2xx fast clear doesn't work with sysmem
rendering. The a22x "normal" clear path doesn't work with sysmem either.
