[sheepdog] [PATCH 1/3] sheep/kv: initialize return code in onode_populate_data()

[Robin Dong]

From: Robin Dong <sanbai at taobao.com>

When we upload a small inlined-object, the function onode_populate_data()
will only return the variable 'ret' which has not been initialized.
So, we should set 'ret' to SD_RES_SUCCESS firstly.
