Remove mark_ttys function and fix tty_display_info initialization.

Browse source 
* lisp.h (mark_ttys): Remove prototype.
* alloc.c (Fgarbage_collect): Remove redundant (and the only) call
to mark_ttys because all possible values of 'top_frame' slot are
the frames which are reachable from Vframe_list.
* term.c (mark_ttys): Remove.
(init_tty): Safely initialize 'top_frame' slot with Qnil.
