Jiri Slaby (SUSE) a81bfb86d1 tty: vt: make consw::con_switch() return a bool 
[ Upstream commit 8d5cc8eed7 ]

The non-zero (true) return value from consw::con_switch() means a redraw
is needed. So make this return type a bool explicitly instead of int.
The latter might imply that -Eerrors are expected. They are not.

And document the hook.
