Hou Wenlong c667a3baed KVM: x86/mmu: Move round_gfn_for_level() helper into mmu_internal.h ...

Rounding down the GFN to a huge page size is a common pattern throughout
KVM, so move round_gfn_for_level() helper in tdp_iter.c to
mmu_internal.h for common usage. Also rename it as gfn_round_for_level()
to use gfn_* prefix and clean up the other call sites.
