Fix accessing the name of a nested struct definition

When generating an error message about the struct nesting limit, the
code should make sure that the struct definitions are not nested.
While nested struct definitions by themselves are also an error,
they're not a syntax error so parsing will continue after encountering
them.

This fixes a regression from commit: Don't allocate name strings for
empty symbols.
