virglrenderer regression in commit ad4f0f1941677c

[Rob Herring]

Hi,

This commit in virglrenderer causes a regression in Android for me.
The parameters that get passed in are last_level = 8, width = 1. I'm
not really sure if this is valid (I'm guessing there should be some
min width?), or where I should be looking to fix this. Any ideas?

    renderer: reject large LOD values

    Or we could sit for a very long time in some further loops.

    Fix found thanks to american fuzzy lop.
