st/mesa: use base level size as "guess" when available
When an applications specifies mip levels _before_ setting a mipmap texture
filter, we will initially guess a single texture level. When the second
level
image is created, we try to allocate the full texture -- however, we get
the
base level size guess wrong if that size is odd. This leads to yet another
re-allocation of the texture later during st_finalize_texture.
Even worse, this re-allocation breaks a (reasonable) assumption made by
st_generate_mipmaps, because the re-allocation in the finalization call
will
again allocate a single-level pipe texture (based on the non-mipmap texture
filter!). As a result, mipmap generation fails in interesting ways.
All of this can be avoided by just using the fact that we already know the
size of the base level.
