[PATCH v1] net/af_xdp: make umem configure code more readable

[Haiyue Wang]

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'
        }
