[PATCH] x86: Fix excessive MSR print out when show_msr is notspecified

From: Yinghai Lu

Dave found:
| During bootup, I now have 162 messages like this..
| [ 0.227346] MSR0000001b: 00000000fee00900
| [ 0.227465] MSR00000021: 0000000000000001
| [ 0.227584] MSR0000002a: 00000000c1c81400
| commit 21c3fcf3e39353d4f21d50e257cc74f3204b1988 looks suspect.
| It claims that it will only print these out if show_msr= is passed,
| but that doesn't seem to be the case.

Fix it by changing to the version that check index.
