Some asserts introduced as part of JDK-8223213 [1] don't take into 
account the case when the class which participates in class 
intialization barrier is in error state (class initialization failed 
with an exception).

Proposed fix adjusts the asserts, plus slightly improves handling of 
cases when classes in error state are encountered.

Testing: hs-precheckin-comp, tier1-4
