Change subject: Log (M)CS UL update errors

Log (M)CS UL update errors

Previously some of the errors in update_cs_ul() call were silently
ignored. Let's log all those as errors with appropriate message.

Note: test output needs updating because we do not (yet) set proper meas
struct in TBF tests. That's likely wrong but it's better to update tests
in a separate commit.
