    xl: show full value of cpu_khz in xl info output
    
    The exact value of cpu_khz can only be obtained via 'xl dmesg', and
    therefore can be lost after some time. 'xl info' truncates the value to
    full MHz. Adjust the output to show the full khz value.
    This helps the host admin to track how a host has calibrated itself. The
    value of cpu_khz is used during live migration for the decision if
    access to TSC should be emualted.
    
    Commit eb5277a30e ("bitkeeper revision 1.959.1.4
    (40d04a87acOb29u-5Y5OxMhHvP2x9g)" gives no hint why cpu_mhz instead of
    cpu_khz was chosen.
