x86/mce: Remove redundant check from mce_device_create()

mce_device_create() is called only from mce_cpu_online() which in turn
will be called iff MCA support is available. That is, at the time of
mce_device_create() call it's guaranteed that MCA support is available.
No need to duplicate this check so remove it.
