In testpatchentrypoints, remove the additional calls to glVertex3fv after releasing the current context. libGLdispatch doesn't unpatch entrypoints from __glDispatchLoseCurrent anymore, so those calls will still increment the __glXSawVertex3fv counter. This means that it no longer tests entrypoint unpatching, but fixing that would require multiple vendor libraries, which with GLX requires multiple screens.
