Fixes #17039 - ldObj checks node/nodeAddr access (#17123)

Browse source 
Checked field expressions, such as an object variant field access results in
occasionally broken address analysis crashing the VM. This guard added here
mimics guarded access in ldObjAddr as well. This is to prevent a crash, while a
fix is devised.
