bgpd: Fix condition allowas-in in rsclient code

Currently when you set neighbour's 'allowas-in' option on route server side
you get redistribution of the prefixes from this neighbour's table into all
neighbour's tables which have the same AS number. I think that wanted behaviour
is to allow import prefixes from neighbour's tables with the same AS num
into neighbour which has 'allowas-in' option set.
