This patch adds a test case, as shown below, for the verifier error
"more than one arg with ref_obj_id".
0: (b7) r2 = 20
1: (b7) r3 = 0
2: (18) r1 = 0xffff92cee3cbc600
4: (85) call bpf_ringbuf_reserve#131
5: (55) if r0 == 0x0 goto pc+3
6: (bf) r1 = r0
7: (bf) r2 = r0
8: (85) call bpf_tcp_raw_gen_syncookie_ipv4#204
9: (95) exit
This error is currently incorrectly reported as a verifier bug, with a
warning. The next patch in this series will address that.
