    x86/mpparse: Don't print "limit reached" for every subsequent processor
    
    When you boot Xen with the default 256 NR_CPUS, on a box with rather more
    processors, the resulting spew is unnecesserily verbose.  Instead, print the
    message once, e.g:
    
     (XEN) ACPI: X2APIC (apic_id[0x115] uid[0x115] enabled)
     (XEN) WARNING: NR_CPUS limit of 256 reached - ignoring further processors
     (XEN) ACPI: X2APIC (apic_id[0x119] uid[0x119] enabled)
     (XEN) ACPI: X2APIC (apic_id[0x11d] uid[0x11d] enabled)
     (XEN) ACPI: X2APIC (apic_id[0x121] uid[0x121] enabled)
