[ Upstream commit 33adf80f5b52e3f7c55ad66ffcaaff93c6888aaa ]
Fix the following warning seen on GCC 7.3: kunit/test-test.o: warning: objtool: kunit_test_unsuccessful_try() falls through to next function kunit_test_catch()
kunit_try_catch_throw is a function added in the following patch in this series; it allows KUnit, a unit testing framework for the kernel, to bail out of a broken test. As a consequence, it is a new __noreturn function that objtool thinks is broken (as seen above). So fix this warning by adding kunit_try_catch_throw to objtool's noreturn list.

I don't think this change should be backported. This patch is to ignore an erroneous warning introduced by KUnit; it serves no purpose prior to the KUnit patches being merged.
I'll drop it, thanks!
