[PATCH bpf-next 4/5] selftests/bpf: Use -1 as token_fd in map create failure test

[Leon Hwang]

Because 0xFF can be an open BPF token fd in the test runner that will fail
test_invalid_token_fd(), change token_fd from 0xFF to -1 to avoid such
test failure.

Fixes: f675483cac1d ("selftests/bpf: Add tests to verify map create failure 
log")
