The linux-5.10-y backport of commit b377c66ae350 ("x86/retpoline: Add
NOENDBR annotation to the SRSO dummy return thunk") misplaced the new
NOENDBR annotation, repeating the annotation on __x86_return_thunk,
rather than adding the annotation to the !CONFIG_CPU_SRSO version of
srso_alias_untrain_ret, as intended.
Move the annotation to the right place.
