Fix format-string mismatch in load_user_profile debug log

The debug3 on LoadUserProfileW failure had format "%s %S %d" (three
specifiers) but only two arguments. %S consumed GetLastError()'s DWORD
as a wide-string pointer and wcsnlen dereferenced it, crashing
sshd-session post-auth.

Only visible where LoadUserProfileW actually fails (e.g. WinPE, which
has no user-profile service), so regular Windows was unaffected.
