pcsx2: Fix inconsistent framelimiter/vsync interaction

If emulation is paused and resumed, vsync may become enabled even if the
frame limiter is currently disabled. This state persists until the
settings are changed or the hotkeys are used.

Fix the inconsistent framelimiter/vsync behaviour so that vsync isn't
enabled whenever the framelimiter is disabled, which matches the
behaviour in the rest of the code.
