Mark Johnston b577047027 mca: Handle inconsistent CMCI capability reporting
A BIOS bug may apparently cause the BSP to report that it does not
implement CMCI, with some APs reporting that they do.  In this scenario,
avoid a NULL pointer dereference that occurs in cmci_monitor() because
cmc_state was not allocated by the BSP.
