KVM: MMU: Fix off-by-one calculating large page count
upstream commit: 99894a799f09cf9e28296bb16e75bd5830fd2c4e
The large page initialization code concludes there are two large pages spanned
by a slot covering 1 (small) page starting at gfn 1. This is incorrect, and
also results in incorrect write_count initialization in some cases (base = 1,
npages = 513 for example).
