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.
