Subject: [PATCH v3 03/21] KVM: x86/mmu: Use consistent "mc" name for kvm_mmu_memory_cache locals

Use "mc" for local variables to shorten line lengths and provide
consistent names, which will be especially helpful when some of the
helpers are moved to common KVM code in future patches.

No functional change intended.
