Nicola Murino b25012b37b ssh: enforce nil Permissions when returning PartialSuccessError
In serverAuthenticate, the permissions variable is reset to nil at the
beginning of the authentication loop. If an authentication callback
returns a PartialSuccessError along with non-nil Permissions, those
permissions are currently silently discarded before the next
authentication step.

This change returns an error if a callback returns both a PartialSuccessError
and non-nil Permissions, preventing API misuse where the user might
erroneously expect those permissions to be preserved or merged into the
final session permissions.

This issue was found during a security audit by NCC Group Cryptography
Services, sponsored by Teleport.

Fixes golang/go#79562
Fixes CVE-2026-39828
