Lukas Wunner 396786af1c tools: ynl-gen: Allow multi-attr without nested-attributes again ...

Since commit ce6cb8113c ("tools: ynl-gen: individually free previous
values on double set"), specifying the "multi-attr" property raises an
error unless the "nested-attributes" property is specified as well:

  File "tools/net/ynl/./pyynl/ynl_gen_c.py", line 1147, in _load_nested_sets
    child = self.pure_nested_structs.get(nested)
                                         ^^^^^^
  UnboundLocalError: cannot access local variable 'nested' where it is not associated with a value

This appears to be a bug since there are existing specs which omit
"nested-attributes" on "multi-attr" attributes.  Also, according to
Documentation/userspace-api/netlink/specs.rst, multi-attr "is the
recommended way of implementing arrays (no extra nesting)", suggesting
that nesting should even be avoided in favor of multi-attr.

Fix the indentation of the if-block introduced by the commit to avoid
the error.
