kernel-doc: Add unary operator * to $type_param_ref

Browse Source 
In kernel-doc comments, unary operator * collides with Sphinx/
docutil's markdown for emphasizing.

This resulted in additional warnings from "make htmldocs":

    WARNING: Inline emphasis start-string without end-string.

, as reported recently [1].

Those have been worked around either by escaping * (like \*param) or by
using inline-literal form of ``*param``, both of which are specific
to Sphinx/docutils.

Such workarounds are against the kenrel-doc's ideal and should better
be avoided.

Instead, add "*" to the list of unary operators kernel-doc recognizes
and make the form of *@param available in kernel-doc comments.
