From: Matthew Brost <matthew.brost@xxxxxxxxx> Remove bogus GEM_BUG_ON which compared kernel context timeline seqno to seqno in memory on engine PM unpark. If a GT reset occurred these values might not match as a kernel context could be skipped. This bug was hidden by always switching to a kernel context on park (execlists requirement).
