samples/bpf: Fix xdp_redirect_map egress devmap prog
LLVM compiler optimized out the memcpy in xdp_redirect_map_egress,
which caused the Ethernet source MAC-addr to always be zero
when enabling the devmap egress prog via cmdline --load-egress.
Issue observed with LLVM version 14.0.0
- Shipped with Fedora 36 on target: x86_64-redhat-linux-gnu.
In verbose mode print the source MAC-addr in case xdp_devmap_attached
mode is used.
