meta: Don't use fixed-function to decompress array textures
Array textures can't be used with fixed-function, so don't. Instead,
just drop the decompress request on the floor. This is no worse than
what was done previously because generating the GL error (in
_mesa_set_enable) broke everything anyway.
A later patch will get GL_TEXTURE_2D_ARRAY targets working.
