Don't switch to a vertex array object of 0.

This causes glDrawArrays to fail in core profile, and thus on OS X, see:

There must be something bound, even though it is not used.

Fixes #7599.  I'm not sure this is actually the best way to fix it,
since AFAICT it makes a nonobvious assumption that *something* will be
bound before the first attributeless rendering in
TextureConverter::DecodeToTexture, but it's what degasus suggested and
seems to work.
