[PATCH] Fix oops with nmi-watchdog=2

Contributions from  Zarakin <zarakin@hotpop.com>

Intel removed two msrs: MSR_P4_IQ_ESCR_0|1 (0x3ba/0x3bb), P4 model >= 3.  See
Intel documentation Vol.  3 System Programming Guide Appendix B.

nmi_watchdog=2 oopsed at boot time and oprofile at driver load.

Avoid touching them when model >= 3.
