gallium/util: Save and restore vertex buffer state in util_gen_mipmap.
Calling glGenerateMipmap could overwrite vertex buffer state, leading
to incorrect rendering or crashes depending on the Gallium driver.
This was happening on WebGL Conformance test texture-size.
Before 784dd51198433e5c299da4a7742c68d21d68d1c1 this was covered up
by redundant vertex buffer validation.
