    nfscl: Add a console message for session recovery
    
    The NFSv4.1/4.2 client does recovery when it receives a
    NFSERR_BADSESSION reply from the server.  If the server has
    not rebooted, this is often caused by multiple clients using
    the same /etc/hostid and, as such, not being recognized as
    different clients by the server.
    
    This trivial patch adds a console message to suggest that
    client's /etc/hostid's need to be checked for uniqueness.
    
    (cherry picked from commit 0685c73cfe88b94d60b1b2ddfdb36c684a008006)
