[sheepdog] [PATCH 2/2] sheep: fix 'collie cluster cleanup' crash in gateway-only node

[levin li]

From: levin li <xingke.lwp at taobao.com>

In gateway-only node, store driver maybe unitialized after restart,
so cluster_cleanup() in gateway-only node crashed when we try to
call sd_store->cleanup()
