Fixes https://github.com/spring-projects/spring-integration/issues/8786 If `FtpSession.readRaw()` fails, the next `FtpSession.finalizeRaw()` call would lead to `FTPClient.completePendingCommand()` failure since there is no command to finish. * Fix `FtpSession.finalizeRaw()` to exit earlier positively in case of `FTPReply.isNegativePermanent()` for the current reply code set by the failure from a previous `FtpSession.readRaw()` **Cherry-pick to `6.1.x`, `6.0.x` & `5.5.x`**
