[sheepdog] [PATCH] sheep: remove nr_outstanding_reqs/outstanding_data_size from local gateway request

[levin li]

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

Local gateway request doesn't allocate memory for data, so outstanding_data_size
is useless, nr_outstanding_reqs is also useless here, and as alloc_local_req() is
called in worker thread, it may cause race, so this patch remove them from local
gateway request path.
