[sheepdog] [PATCH] recovery: fix a bug of get_vnode_info_epoch() which gives a bad node number

[levin li]

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

When local epoch file does not exist, sheep tries to read from remote node
by epoch_log_read_remote(), which directly returns the number of node, not
the length of node data.
