KVM: MMU: Make the way of accessing lpage_info more generic
Large page information has two elements but one of them, write_count, alone is accessed by a helper function. This patch replaces this helper function with more generic one which returns newly named kvm_lpage_info structure and use it to access the other element rmap_pde.
