Dongli Zhang 428292ec7a xenbus: req->err should be updated before req->state ...

[ Upstream commit 8130b9d5b5 ]

This patch adds the barrier to guarantee that req->err is always updated
before req->state.

Otherwise, read_reply() would not return ERR_PTR(req->err) but
req->body, when process_writes()->xb_write() is failed.
