knfsd: rpcgss: RPC_GSS_PROC_ DESTROY request will get a bad rpc

If I send a RPC_GSS_PROC_DESTROY message to NFSv4 server, it will reply with a
bad rpc reply which lacks an authentication verifier.  Maybe this patch is
needed.

Send/recv packets as following:

send:

RemoteProcedureCall
    xid
    rpcvers = 2
    prog = 100003
    vers = 4
    proc = 0
    cred = AUTH_GSS
        version = 1
        gss_proc = 3 (RPCSEC_GSS_DESTROY)
        service  = 1 (RPC_GSS_SVC_NONE)
    verf = AUTH_GSS
        checksum

reply:

RemoteProcedureReply
    xid
    msg_type
    reply_stat
    accepted_reply
