Fails to build with gcc 9.1.0 due to
-Werror=address-of-packed-member. One example:
usbip_network.c: In function 'usbip_net_pack_usb_device':
usbip_network.c:79:32: error: taking address of packed member of 'struct usbip_usb_device' may result in an unaligned pointer value [-Werror=address-of-packed-member]
79 | usbip_net_pack_uint32_t(pack, &udev->busnum);
| ^~~~~~~~~~~~~
All of these are code which is explicitly packing a struct, so
add -Wno-address-of-packed-member to EXTRA_CFLAGS to disable this
warning.
