Corrected Machine Check Interrupt (CMCI) can be configured via the per Machine Check bank registers: IA32_MCI_CTL2. To emulate IA32_MCI_CTL2 registers, it's necessary to introduce another array mci_ctl2_banks in analogy to the mce_banks array under struct kvm_vcpu_arch. This patch updates the allocation of mce_banks with the array allocation API (kcalloc) as a precedent for the later mci_ctl2_banks.
