Subject: [PATCH] [decompiler] fix local_vars assert on static lambda (#1895)

Fixes a crash when there's a `(new 'static 'something :field <some
anonymous function with a particular set of errors in the decompler>)`.
The output will now be
```
 (set! *duck-mods* (new 'static 'surface
                      :name 'duck
...
                      :mult-hook <lambda at L615>
                      :flags (surface-flag duck)
                      )
```
