[PATCH v3] kernel-doc: Added "*" in $type_constants2 to fix 'make htmldocs' warning.

[Utkarsh Tripathi <utripathi2002@gmail.com>]

Fixed: WARNING: Inline literal start-string without end-string in 
Documentation/core-api/workqueue.rst

Added "*" in $type_constants2 in kernel-doc script to include "*" in the
conversion to hightlights.
Previously: %WQ_* -->  ``WQ_``*
After Changes: %WQ_* -->  ``WQ_*``
Need for the fix: ``* is not recognized as a valid end-string for inline literal.

> The kernel-doc script uses the $type_constant2 variable to match
> expressions used to find embedded type information.
