    kexec: suppress bogus warning
    
    Till now "crashkernel=1G-16G:1M" causes
    
    (XEN) crashkernel: '' ignored
    (XEN) parameter "crashkernel" has invalid value "1G-16G:1M", rc=-22!
    
    Don't emit the "ignored" warning when there's no placement specification
    and the tail of the specified option is actually empty.
