simple reproduccer to simplify the debugging process.

Hi,

I have created the simple reproducer because debugging the chrome not very
convenient.

My current progress in this issue:

I managed to reproduce this issue in the following way:
1. Use shader program which is used at least one 'texture sample' in FS instead
of 'FF'.
2. Setup following property for texture GL_TEXTURE_MIN_FILTER = GL_LINEAR or
GL_NEAREST
3. The program must upload level 2 = 4x4, 1 = 2x2, 0 = 1x1. The pixels values
is not matter but must be uploaded and sequence of uploading is very matter,
firstly level 2 then 1 and lastly 0.
4. The last operation which should cause the assertion is glDrawArrays which
uses shader and texture mentioned above to draw some rectangle.

I found out that when we try to re-create miptree in
'intel_finalize_mipmap_tree' function we don't consider the 'base level' in
width0, height0, depth0 calculations.
I not very familiar with this part of the mesa code but I found that the
'intel_miptree_create_for_teximage' function consider the 'base level'. 
So I tried to do it in 'intel_finalize_mipmap_tree' and that fixes this issue
for me. So I hope that this is a possible fix:
