bpf: fix missing bpf_check_uarg_tail_zero in BPF_PROG_TEST_RUN Commit b0b9395d865e ("bpf: support input __sk_buff context in BPF_PROG_TEST_RUN") started using bpf_check_uarg_tail_zero in BPF_PROG_TEST_RUN. However, bpf_check_uarg_tail_zero is not defined for !CONFIG_BPF_SYSCALL: net/bpf/test_run.c: In function ‘bpf_ctx_init’: net/bpf/test_run.c:142:9: error: implicit declaration of function ‘bpf_check_uarg_tail_zero’ [-Werror=implicit-function-declaration] err = bpf_check_uarg_tail_zero(data_in, max_size, size); ^~~~~~~~~~~~~~~~~~~~~~~~ Let's not build net/bpf/test_run.c when CONFIG_BPF_SYSCALL is not set.
