[Mesa-stable] Nomination for 10.6

[Ian Romanick]

Emil,

Are there going to be any more 10.6 releases?  I had intended to mark
the following commit for 10.6 and 11.0, but it looks like I only marked
it for 11.0.  If there's going to be another 10.6, could you add this to
the list?

Thanks.

    meta: Always bind the texture

    We may have been called from glGenerateTextureMipmap with CurrentUnit
    still set to 0, so we don't know when we can skip binding the texture.
    Assume that _mesa_BindTexture will be fast if we're rebinding the same
    texture.

    v2: Remove currentTexUnitSave because it is now unused.  Suggested by
    both Neil and Anuj.
