Subject: selftests/bpf: Fix an unused-but-set-variable compiler warning
Patch-mainline: v5.17-rc1
Git-commit: 21c6ec3d5275a77348b1af0e78cbbed0ee1558d4
References: jsc#PED-1368

When using clang to build selftests with LLVM=1 in make commandline,
I hit the following compiler warning:
  xdpxceiver.c:747:6: warning: variable 'total' set but not used [-Wunused-but-set-variable]
          u32 total = 0;
              ^

This patch fixed the issue by removing that declaration and its
assocatied unused operation.
