KVM: x86/mmu: fix counting of rmap entries in pte_list_add
Fix an off-by-one style bug in pte_list_add() where it failed to
account the last full set of SPTEs, i.e. when desc->sptes is full
and desc->more is NULL.
Merge the two "PTE_LIST_EXT-1" checks as part of the fix to avoid
an extra comparison.
