glx: don't destroy context immediately if it's currently bound
According to the GLXDestroyContext() man page, the context should not immediately be destroyed if it's bound to some thread. Wait until it's unbound to really delete it. The code for doing the later part is already present in MakeContextCurrent() so no change was needed there.
