selftests/xsk: print correct payload for packet dump
[ Upstream commit 2d0b2ae2871ae6d42a9f0a4280e0fb5bff8d38b8 ]
Print the correct payload when the packet dump option is selected. The
network to host conversion was forgotten and the payload was
erronously declared to be an int instead of an unsigned int.
