x86: Fix excessive MSR print out when show_msr is not specified

Dave found:

| During bootup, I now have 162 messages like this..
| [    0.227346]  MSR0000001b: 00000000fee00900
| [    0.227465]  MSR00000021: 0000000000000001
| [    0.227584]  MSR0000002a: 00000000c1c81400

| commit 21c3fcf 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 checks the index.
