socks: fix expected length of SOCKS5 reply
Commit 4a4b63d forgot to set the expected SOCKS5 reply length when the
reply ATYP is X'01'. This resulted in erroneously expecting more bytes
when the request length is greater than the reply length (e.g., when
remotely resolving the hostname).
Closes #5527
