Subject: samples/bpf: Reduce the sampling interval in xdp1_user
Patch-mainline: v5.19-rc1
Git-commit: db69264f983a5890fe8ba20ed4c20dfd4b687615
References: jsc#PED-1377

If interval is 2, and sum - prev[key] = 1, the result = 0. This will
mislead the tester that the port has no traffic right now. So reduce the
sampling interval to 1.
