[PATCH 1/2] KVM: VMX: Keep registers read/write consistent with definition

[Yang Zhong <yang.zhong@intel.com>]

The kvm_cache_regs.h file has defined inline functions for those general
purpose registers and pointer register read/write operations, we need keep
those related registers operations consistent with header file definition
in the VMX side.
