    smb: Do not show password prompt when using winbind ccache
    
    Recent samba releases seems invoke auth_callback even when using
    cached winbind credentials. It shows password prompt to user, which
    is unexpected. Add one more iteration in the mount procedure just
    for ccache. This will unfortunately make one fail attempt if the
    winbind ccache is not configured, but I don't see better way to
    fix this.
