mesa: raise GL_INVALID_OPERATION in glGenerateMipmap for missing base image
This seems to be expected by the WebGL texture-mips test. The error makes
sense, but I haven't found (yet) any OpenGL documentation specifying this
error condition.
See http://bugs.freedesktop.org/show_bug.cgi?id=44912
Note: This is a candidate for the 8.0 branch.
