mesa: fix proxy textures not working with default texture binding

When working with the glTexStorage*() functions, the error checking
checks that a non-default (i.e., non-zero) texture is currently bound.
However, this check made glTexStorage*() functions fail with proxy
textures when the default texture is bound. Proxy textures do not care
about the current texture bindings so for them this check should not
be done.
