Subject: [PATCH 06/13] objtool: Remove --unret dependency on --rethunk
With unret validation enabled and IBT/LTO disabled, objtool runs on TUs
with --rethunk and on vmlinux.o with --unret. So this dependency isn't
valid as they don't always run on the same object.
This error never triggered before because --unret is always coupled with
--noinstr, so the first conditional in opts_valid() returns early due to
opts.noinstr being true.
