[PATCH] workqueue: remove unused WORK_CPU_END

[PATCH] workqueue: remove unused WORK_CPU_END

[Lai Jiangshan]

WORK_CPU_END is totally unused since 4e8b22bd. It should be removed.

After it is removed, the comment "special cpu IDs" is not precise due to
there is only one special CPU ID (WORK_CPU_UNBOUND) left, so we also
change this comment to the description for WORK_CPU_UNBOUND.

Please use 12_CHAR_PREFIX_OF_SHA1 ("SUBJ") when referring to other
commits.
