streams/xp_socket: fix clang build error with enum usage on bool condition.

Fix targeted for oses defining those flags as enums (like Linux/glibc).

`error: converting the enum constant to a boolean [-Werror,-Wint-in-bool-context]
                                } else if ((!sslsock->ssl_active && value == 0 && (MSG_DONTWAIT || !sslsock->s.is_blocked)) ||`

Closes #8895.
