mm: hugetlb: fix type of hugetlb_treat_as_movable variable

hugetlb_treat_as_movable declared as unsigned long, but
proc_dointvec() used for parsing it:

static struct ctl_table vm_table[] = {
                .procname	= "hugepages_treat_as_movable",
                .data		= &hugepages_treat_as_movable,
                .maxlen		= sizeof(int),
                .mode		= 0644,
                .proc_handler	= proc_dointvec,

This seems harmless, but it's better to use int type here.
