Kyle Brenneman 73b38ce822 tests: Fix testpatchentrypoints.
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.
