perf_counter, x86: Fix lapic printk message
Instead of this garbled bootup on UP Pentium-M systems:
[ 0.015048] Performance Counters:
[ 0.016004] no Local APIC, try rebooting with lapicno PMU driver, software counters only.
Print:
[ 0.015050] Performance Counters:
[ 0.016004] no APIC, boot with the "lapic" boot parameter to force-enable it.
[ 0.017003] no PMU driver, software counters only.
