selftests: bpf: Ignore FIN packets for reuseport tests
commit 8bec4f665e0baecb5f1b683379fc10b3745eb612 upstream.
The reuseport tests currently suffer from a race condition: FIN
packets count towards DROP_ERR_SKB_DATA, since they don't contain
a valid struct cmd. Tests will spuriously fail depending on whether
check_results is called before or after the FIN is processed.
Exit the BPF program early if FIN is set.
