According to GLES 2.0.24 Spec, there is no hard limit as level < log2(MAX_TEXTURE_SIZE). It only says the maximum allowable width/height may be zero for image arrays of any level-of-detail greater than log2(MAX_TEXTURE_SIZE). In this case, we should remove the code that checks the level upper limit.

Would have been nice to say some version of this in the ChangeLog (imo) as it would help anyone trying to understand why the change was done. Regardless, at least it is in the bug so they can't find it if needed.
