Revert "added got_allow_ip() wrapper around have_allow_ip() to fix an exported symbol issue noticed by Franck"

This reverts commit e57cfa2e23.  This is done
because libfko now restricts the symbols it exports to only those functions
that should be visible when making use of the library - internal libfko
functions should not be exported.
