KVM: x86/mmu: Use gfn_t in kvm_flush_remote_tlbs_range() 



Use gfn_t instead of u64 for kvm_flush_remote_tlbs_range()'s parameters,
since gfn_t is the standard type for GFNs throughout KVM.

Opportunistically rename pages to nr_pages to make its role even more
obvious.

No functional change intended.
