[sheepdog] [PATCH] cluster/local: don't process leave event of gateway node

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

We must not call sd_leave_handler() when the gateway node leaves cluster.  It is
because we already processed the event when the node became gateway.

The local driver can pass tests/048 with this patch.
