Subject: [PATCH V2 4/5] x86/mce: Clarify comments regarding deferred error

The Deferred field indicates if we have a Deferred error.
Deferred errors indicate errors that hardware could not
fix. But it still does not cause any interruption to program
flow. So it does not generate any #MC and UC bit in MCx_STATUS
is not set.

Fixing comment here. No functional change
