[Mesa-dev] [PATCH] i965: consider a 'base level' when calculating width0, height0, depth0

[asimiklit.work at gmail.com]

From: Andrii Simiklit <andrii.simiklit at globallogic.com>

I guess that when we calculating the width0, height0, depth0
to use for function 'intel_miptree_create' we need to consider
the 'base level' like it is done in the 'intel_miptree_create_for_teximage'
function.
