[PATCH 2/2] d3d9: Upload the relevant texture in d3d9_texture_gen_auto_mipmap().

[Zebediah Figura]

From: Zebediah Figura

Instead of uploading all currently bound textures. Besides being redundant, this
would generate mipmaps for an uninitialized texture, and subsequently trying to
render from nonzero mipmap levels would yield uninitialized data.
