bgpd: fix use of free memory by update_rsclient
* bgp_route.c: (bgp_static_update_rsclient) BGP sometimes crashes when
removing route server client because of use after free.
The code to update rsclient created a local static copy of bgp attributes
but neglected to handle the extra information pointer. The extra
information was getting freed by bgp_attr_unintern() and reused later when
the copy was passed to bgp_attr_intern().
The fix is to use the attr_dup function to create a copy of the extra
information, then clean it up.
