bgpd: fix parsing of graceful restart cap. (#663)

"While setting up a testbed, I ran across a little problem in the
parsing of the "graceful restart" BGP capability that resulted in
Quagga not actually activating it for the peer in question - when
the peer sent a single AFI/SAFI block."

* bgp_open.c
  * bgp_capability_restart(): actually process the last AFI/SAFI block
