[U-Boot] [PATCH 1/1] net: remove superfluous __packed attribute

[Heinrich Schuchardt]

struct ip_udp_hdr is naturally packed. There is no point in adding a
__packed attribute. With the attribute the network stack does not compile
using GCC 9.2.1:

net/net.c: In function ‘net_process_received_packet’:
net/net.c:1288:23: error: taking address of packed member of ‘struct
ip_udp_hdr’ may result in an unaligned pointer value
[-Werror=address-of-packed-member]
 1288 |    sumptr = (ushort *)&(ip->udp_src);
      |                       ^~~~~~~~~~~~~~

So let's remove the attribute.
