+1) Remove an early failure return for GSSAPI authentication attempts

+valid vs invalid accounts.
+
+2) Fix a situation where some GSSAPI requestes were not correctly
+subjected to MaxAuthTries.
+
+3) Fix a moderate pre-authentication resource DoS related to #2.

+Add missing logging for error cases.

+CVE: CVE-2026-60000
+Upstream-Status: Backport [https://github.com/openssh/openssh-portable/commit/5d04ca6af739b82fd30d84d2783ca802ebfa1192]
+
+Backport Changes:
+- Omitted the upstream OpenBSD revision-only hunk in auth2-gss.c and
+  retained the Wrynose OpenSSH 10.3p1 revision because this stable
+  backport carries only the functional security change.
+
+(cherry picked from commit 5d04ca6af739b82fd30d84d2783ca802ebfa1192)

This is a oneline manpage patch for "Windows Active Directory
environments.".

I'm not expert in GSSAPI but can we even trigger this?
If not, I think this should be handled with a CVE_STATUS.

I'll hold this patch in the meantime.
