Change subject: xua_find_as_for_asp(): Optimize lookup

xua_find_as_for_asp(): Optimize lookup
Instead of looking up on all AS configured in an instance, look up on
the subset associated to the ASP we are looking up for.
Since we are also not looking a 2nd pass to then validate if ASP and
returned AS is related, in worst case this would split lookup complexity
by half.
