Borislav Petkov (AMD)andGreg Kroah-Hartman 7ef6a7f9b3 x86/retpoline: Add NOENDBR annotation to the SRSO dummy return thunk ...

commit b377c66ae3 upstream.

srso_alias_untrain_ret() is special code, even if it is a dummy
which is called in the !SRSO case, so annotate it like its real
counterpart, to address the following objtool splat:

  vmlinux.o: warning: objtool: .export_symbol+0x2b290: data relocation to !ENDBR: srso_alias_untrain_ret+0x0
