[RFA] top.c: initialize other UIs before cli

[Keith Seitz <keiths@cygnus.com>]

Hi,

There is currently a little problem with init_ui_hook: if the UI fails to
initialize (and we should fall back to "gdb -nw"), then the CLI will NOT
get initialized properly.

This results because init_ui_hook does not return any status indicating
the failure.

This simple change will correct this anomaly without altering init_ui_hook
semantics, i.e., it is absolutely the least intrusive.

?
