In exceptional circumstances, an MCA exception will trigger when the freelist is exhausted. In such a case, no error will be logged on the list and 'mca_count' will not be incremented. Prior to this patch, all CPUs that received the exception would spin forever. With this change, the CPU that detects the error but finds the freelist empty will proceed to panic the machine, ending the deadlock. A follow-up to r260457.
