[Mesa-dev] [PATCH v2] radeon: fixed division by zero

[Jakob Sinclair]

Coverity is getting a false positive that a division by zero can occur
here. This change will silence the Coverity warnings as a division by zero
cannot occur in this case.

Changes since V1: We realised that Coverity was actually giving out a false
positive and therefor we can just use assert here because max_width and max_height
should never be below 1.
