Subject: [PATCH] nfsd41: error out when client sets maxreq_sz or maxresp_sz
 too small

According to RFC5661, 18.36.3,

 "if the client selects a value for ca_maxresponsesize such that
  a replier on a channel could never send a response,the server
  SHOULD return NFS4ERR_TOOSMALL in the CREATE_SESSION reply."

So, error out when the client sets a maxreq_sz less than the minimum
possible SEQUENCE request size, or sets a maxresp_sz less than the
minimum possible SEQUENCE reply size.
