svcrpc: make xpo_recvfrom return only >=0
The only errors returned from xpo_recvfrom have been -EAGAIN and -EAFNOSUPPORT. The latter was removed by a previous patch. That leaves only -EAGAIN, which is treated just like 0 by the caller (svc_recv). So, just ditch -EAGAIN and return 0 instead. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
