[bgpd] fix a couple of trivial compiler warnings

2008-07-22 Paul Jakma <paul.jakma@sun.com>

	* bgp_community.c: (community_str2com) assigns defaults to local
	  vars
	* bgp_attr.c: (bgp_attr_parse) match format specifier to arg
	* bgp_table.{c,h}: (bgp_table_top) can take a * to a const, quelling
	  warning in bgp_route.c
