    tools/xenstored: remove the "-R" command line option
    
    The "-R" (no recovery) command line option enables to omit fixing the
    node store in case of detected inconsistencies.
    
    This might have been of interest in the past, when the node data base
    was kept in a file, but now the usability of this option is zero.
    
    Remove the "-R" option.
