Move typedef unsigned long __kernel_size_t out of ifdef condition
IoT.js uses this type, so remove iotivity ifdef condition
#ifndef __ASSEMBLY__
+typedef unsigned long __kernel_size_t;
+
#ifdef CONFIG_ENABLE_IOTIVITY
typedef int wint_t;
-typedef unsigned long __kernel_size_t;
typedef unsigned short __kernel_sa_family_t;
typedef unsigned short __u16;
