KVM: x86/mmu: Remove function comments above clear_dirty_{gfn_range,pt_masked}()
Drop the comments above clear_dirty_gfn_range() and
clear_dirty_pt_masked(), since each is word-for-word identical to the
comment above their parent function.
Leave the comment on the parent functions since they are APIs called by
the KVM/x86 MMU.
No functional change intended.
