console: Avoid dereferencing NULL active_console
The console_select() function does not check that active_console is
non-NULL before dereferencing it. When invoked with qemu -nodefaults it
is possible to hit this case.
This patch checks that active_console is non-NULL before stashing away
the old console dimensions in console_select().
