On older kernels this returns -ENOPROTOOPT for SOCK_STREAM too, which scm_inq.basic/partial_read currently treat as a failure. Enabling SO_INQ here is only a precondition for the actual test: the SCM_INQ/ioctl(SIOCINQ) consistency checks that follow. SKIP when the precondition itself isn't met, rather than asserting it succeeds.
