The `kunit_do_failed_assertion` function passes its `struct kunit_assert` argument to `kunit_fail`. This one, in turn, calls its `format` field passing the assert again as a `const` pointer.
Therefore, the whole chain may be made `const`.

Thanks for this, the code definitely should have been this way from the start.
I had wanted to make this change but mistakenly thought the format func took it via non-const for some reason. I must have misread it once and got it into my head that we were leaving the door open for mutable child structs (which sounds like a bad idea).
