x86: Sanitize smp_record and move it to x86_init_ops

Browse Source 
The x86 quirkification introduced an extra ugly hackery with a
variable pointer in the mpparse code. If the pointer is initialized
then it is dereferenced and the variable set to 0 or incremented.

Create a x86_init_ops function and let the affected numaq code
hold the function. Default init is a setup noop.
