NFS: Fix false error return from nfs_callback_up() if ipv6.ko is not available
Clear "ret" if the error return from svc_create_xprt(AF_INET6) was -EAFNOSUPORT. Otherwise, callback start-up will succeed, but nfs_callback_up() will return -EAFNOSUPPORT anyway, and the first NFSv4 mount attempt after a reboot will fail. Bug introduced by commit f738f517 in 2.6.30-rc1. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
