Subject: [PATCH] socks: return error if hostname too long for remote resolve

Prior to this change the state machine attempted to change the remote
resolve to a local resolve if the hostname was longer than 255
characters. Unfortunately that did not work as intended and caused a
security issue.

Bug: https://curl.se/docs/CVE-2023-38545.html
