x86, MCE: Do not taint when handling correctable errors

Browse source

Correctable errors are considered something rather normal on
modern hardware these days. Even more importantly, correctable
errors mean exactly that - they've been corrected by the
hardware - and there's no need to taint the kernel since
execution hasn't been compromised so far.

Also, drop tainting in the thermal throttling code for a similar
reason: crossing a thermal threshold does not mean corruption.
