docs: kernel-doc.rst: improve structs chapter

There is a mess on this chapter: it suggests that even
enums and unions should be documented with "struct". That's
not the way it should be ;-)

Fix it and move it to happen earlier.

+Structure, union, and enumeration documentation
+-----------------------------------------------
+
+The general format of a struct, union, and enum kernel-doc comment is::
+
+  /**
+   * struct struct_name - Brief description.
+   * @argument: Description of member member_name.
+   *
+   * Description of the structure.
+   */
+
+On the above, ``struct`` is used to mean structs. You can also use ``union``
+and ``enum``  to describe unions and enums. ``argument`` is used
+to mean struct and union member names as well as enumerations in an enum.
+
+The brief description following the structure name may span multiple lines, and
+ends with a member description, a blank comment line, or the end of the
+comment block.
+
+The kernel-doc data structure comments describe each member of the structure,
+in order, with the member descriptions.
