i965: Don't relayout a texture just for baselevel changes.
As long as the baselevel, maxlevel still sit inside the range we had
previously validated, there's no need to reallocate the texture.
I also hope this makes our texture validation logic much more obvious.
It's taken me enough tries to write this change, that's for sure. Reduces
miptree copy count on a piglit run by 1.3%, though the change in amount of
data moved is much smaller.
