[PATCH 1/2] kconfig/nconf: use the generic menu_get_ext_help()

[Arnaud Lacombe <lacombar@gmail.com>]

nconf is the only front-end which does not use this helper, but prefer to
copy/paste the code. The test wrt. menu validity added in this version of the
code is bogus anyway as an invalid menu will get dereferenced a few line below
by calling menu_get_prompt().

For now, convert nconf to use menu_get_ext_help(), as do every other front-end.
We will deals with menu validity checks properly in a separate commit.
