Currently when we create a file, we spin up an xattr buffer to send along with the create request. If we end up doing an async create however, then we currently pass down a zero-length xattr buffer. Fix the code to send down the xattr buffer in req->r_pagelist. If the xattrs span more than a page, however give up and don't try to do an async create.
