x86, mce: don't set up mce sysdev devices with mce=off

Impact: bug fix, in this case the resume handler shouldn't run which
avoids incorrectly reenabling machine checks on resume

When MCEs are completely disabled on the command line don't set
up the sysdev devices for them either.

Includes a comment fix from Thomas Gleixner.
