Avoid a warning from the QNX QPA plugin.

Browse Source 
The HDMI display on the Playbook is listed, but (normally) unattached, 
and hence generates an error if we attempt to register for events. This 
patch avoids the warning; a future change will actually watch for screens
being attached / detached and update the QPlatformScreens and event
registration correctly.
