Stefan Eissing 66d35ee5d4 lib: avoid reusing unclean connection ... When `curl_easy_cleanup()` is invoked while still being part of a multi handle, the code will auto-remove it. But since the connection was detached first, the code in `curl_multi_remove_handle()` that invalidates dirty connections did not bite. Attach the connection *after* the possible remove from a multi handle, so that connection reuse can be prevented. Add test753 to reproduce and verify the fix. This required adding the new debug env var CURL_FTP_PWD_STOP, to have a transfer return from multi_perform() early with a connection that does not show and pending input.
