do not unnecessarily lock XLayoutManager for menubar changes
The XLayoutManager documentation says that lock() prohibits layout
updates until unlock() is called, so it's not any kind of mutex
or anything, it just allows grouping updates. Which means it's
useless to put around a single call to change menubar visibility.
To make things worse, unlock() will always trigger a layout,
so even if nothing changes, it still does an unnecessary layout
update. And since this gets called from SfxLokHelper::setView(),
it may get called often and it's rather costly.
