RFR: 8365526: Crash with null Symbol passed to SystemDictionary::resolve_or_null

[Coleen Phillimore]

The vm was crashing because the constant pool couldn't find the resolution error in the ResolutionErrorEntry (error field). Multiple threads were adding duplicate entries for nest_host_errors in the case where resolution failed and where there was already a nest host error in the ResolultionErrorEntry.  Add a null check and an assert that we only add a resolution error for nest host errors in the case of success since in the case of failure there will always already be a ResolutionErrorEntry for the failing constant pool and cp index.
Tested with submitted reproducer and tier1-4.
