GC the cn_dbctl_t hook for consoles, it is unused.

This used to make syscons switch to vty0 when we entered DDB but this
was lost in the KDB shuffle.  We may want to bring it back down the road
but it should be done by calling cn_init_t/cn_term_t instead, possibly
with a flag argument saying "Debugger!"
