mesa: Don't crash when destroying contexts created with no visual.
dEQP-EGL.functional.create_context.no_config tries to create a context
with no config, then immediately destroys it. The drawbuffer is never
set up, so we can't dereference it asking if it's double buffered, or
we'll crash on a null pointer dereference.
Just bail early.
Applications using EGL_KHR_no_config_context could hit this.
