kernel-doc: cleanup parameter type in function-typed arguments

A prototype like

    /**
     * foo - sample definition
     * @bar: a parameter
     */
    int foo(int (*bar)(int x,
                       int y));

is currently producing

    .. c:function:: int foo (int (*bar) (int x,                    int y)

       sample definition

    **Parameters**

    ``int (*)(int x,                    int y) bar``
      a parameter

Collapse the spaces so that the output is nicer.
