Fix issue #2420340: if FLAG_SHOW_WHEN_LOCKED, do not show keyguard... 

...go directly to unlock screen

Fix a problem where, when we are moving windows due to a configuration
change, our wait to have the windows get redrawn would also
inadvertently make us think their surfaces should be hidden, leading
to nasty things like the lock screen thinking it should be shown
again (and thus forcing the orientation back to portrait).
