DolphinQt: Only update call stack if paused

This avoids a pseudo infinite loop where CodeWidget::UpdateCallstack
would lock the CPU in order to read the call stack, causing the CPU to
call Host_UpdateDisasmDialog because it's transitioning from running to
pausing, causing Host::UpdateDisasmDialog to be emitted, causing
CodeWidget::Update to be called, once again causing
CodeWidget::UpdateCallstack to be called, repeating the cycle.

Dolphin didn't go completely unresponsive during this, because
Host_UpdateDisasmDialog schedules the emitting of Host::UpdateDisasmDialog
to happen on another thread without blocking, but it was stopping certain
operations like exiting emulation from working.
