Jon TURNEY c745db1674 GLX: Avoid a crash when we have an uninitialized GL context ...

If the GL dispatch table pointer points to glapi_noop_table,
(due to some kind of GL initialization failure), DoGetString(GL_VERSION)
(for example as invoked by glxinfo) will crash as it tries to
do atof() on the null pointer returned by the noop dispatch function
