[Haiyue Wang <haiyue.wang@intel.com>]

The below compile time defined style make the code not so readable, the
first function end block is after "#endif" segment.

	#if defined(XDP_UMEM_UNALIGNED_CHUNK_FLAG)

	xdp_umem_configure()
	{

	#else
	xdp_umem_configure()
	{

	#endif
		'shared code block'
	}
