usbip: Fix unsafe unaligned pointer usage

[ Upstream commit 585c91f40d201bc564d4e76b83c05b3b5363fe7e ]

Fix unsafe unaligned pointer usage in usbip network interfaces. usbip tool
build fails with new gcc -Werror=address-of-packed-member checks.

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);

Fix with minor changes to pass by value instead of by address.
