[PATCH 09/67] ui/console: get the DisplayState from new_console()

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

There is no obvious reason to defer text console initialization. We can
simply take the global display state in new_console().

This simplify somewhat the code to allow moving the VC to a separate unit.
