sockets/network: relax SockAddrIn len check and fix port byte-order to avoid SSBU crashes

- Accept SockAddrIn len in [6, sizeof] and warn instead of asserting to handle libnx/SSBU quirks
- Ensure TranslateFromSockAddrIn sets sin_port via htons(uint16_t) for consistent network byte-order
- Prevents assertion crashes and reduces “Broken pipe” error spam observed in Frozen's SSBU logs
