[sheepdog] [PATCH v2 2/2] dog: fix compile warning

[Robin Dong]

From: Robin Dong <sanbai at taobao.com>

It will report warning:

node.c: In function ‘node_stat’:
node.c:278: warning: ‘last.r.peer_total_rx’ may be used uninitialized in this function
node.c:278: warning: ‘last.r.peer_total_tx’ may be used uninitialized in this function
node.c:278: warning: ‘last.r.peer_total_nr’ may be used uninitialized in this function
node.c:278: warning: ‘last.r.gway_total_rx’ may be used uninitialized in this function
node.c:278: warning: ‘last.r.gway_total_tx’ may be used uninitialized in this function
node.c:278: warning: ‘last.r.gway_total_nr’ may be used uninitialized in this function

when compiling sheepdog. The reason is we forget to initialize argument 'last'.
