The function kvm_arch_mmu_enable_log_dirty_pt_masked() is called by kvm_vm_ioctl_reset_dirty_pages() and kvm_clear_dirty_log_protect(). Both callers already perform a TLB flush after enabling dirty logging, so the TLB flush inside kvm_arch_mmu_enable_log_dirty_pt_masked() is unnecessary. Remove it.
