samples/bpf: deal with EBUSY return code from sendmsg in xdpsock sample

Sendmsg in the SKB path of AF_XDP can now return EBUSY when a packet
was discarded and completed by the driver. Just ignore this message
in the sample application.

Fixes: b4b8faa1ded7 ("samples/bpf: sample application and documentation for AF_XDP sockets")
