Subject: [PATCH 23/24] staging: lustre: Use lnet_is_route_alive for router aliveness

From: Chris Horn <hornc@...y.com>

lctl show_route and lctl route_list will output router aliveness
information via lnet_get_route(). lnet_get_route() should use the
lnet_is_route_alive() function, introduced in e8a1124
http://review.whamcloud.com/7857, to determine route aliveness.
