The vnc code assumes that bgp must have a default instance. This code change checks to make sure that we do before proceeding. It makes no assurances that vnc will behave correctly without a default instance.

Otherwise, if bgp->lock reaches zero, bgp_free() is called and peer->bgp becomes an invalid pointer in the bgp_delete_connected_nexthop() function. To fix this, move the call to bgp_unlock() to the end of peer_free(). Bug exposed by commit 37d361e ("bgpd: plug several memleaks").
