x86, mce: remove incorrect __cpuinit for mce_cpu_features()

Impact: Bug fix on UP

Checkin 6ec68bff3c81e776a455f6aca95c8c5f1d630198:
    x86, mce: reinitialize per cpu features on resume

introduced a call to mce_cpu_features() in the resume path, in order
for the MCE machinery to get properly reinitialized after a resume.
However, this function (and its successors) was flagged __cpuinit,
which becomes __init on UP configurations (on SMP suspend/resume
requires CPU hotplug and so this would not be seen.)

Remove the offending __cpuinit annotations for mce_cpu_features() and
its successor functions.
