Don't let /dev/console be revoked if the TTY below is being closed.

Browse Source 
During startup some of the syscons TTY's are used to set attributes like
the screensaver and mouse options. These actions cause /dev/console to
be rendered unusable.

Fix the issue by leaving the TTY opened when it is used as the console
device.
