selftests/bpf: Fix a test_verifier failure
The following test_verifier subtest failed due to new encoding for BSWAP. $ ./test_verifier ... #99/u invalid 64-bit BPF_END FAIL Unexpected success to load! verification time 215 usec stack depth 0 processed 3 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0 #99/p invalid 64-bit BPF_END FAIL Unexpected success to load! verification time 198 usec stack depth 0 processed 3 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0 Tighten the test so it still reports a failure.
