The proposal removes a second == NULL check on field_name in the case where
OBJ_nid2sn() returns an ASN1_OBJECT.  This is not in a hot path, and the ASM
generated is equal under optimization levels so I don't see the value in the
code churn and the potential for collisions during backpatching around here.
