Context: Currently this macro's name, KUNIT_ASSERTION conflicts with the name of an enum whose values are {KUNIT_EXPECTATION, KUNIT_ASSERTION}.
It's hard to think of a better name for the enum, so rename this macro. It's also a bit strange that the macro might do nothing depending on the boolean argument `pass`. Why not have callers check themselves?
This patch: Moves the pass/fail checking into the callers of KUNIT_ASSERTION, so now we only call it when the check has failed. Then we rename the macro the _KUNIT_FAILED() to reflect the new semantics.
