oprofile/x86: remove node check in AMD IBS initialization
Standard AMD systems have the same number of nodes as there are northbridge devices. However, there may kernel configurations (especially for 32 bit) or system setups exist, where the node number is different or it can not be detected properly. Thus the check is not reliable and may fail though IBS setup was fine. For this reason it is better to remove the check.
