[PATCH 1/2] workqueue: Have 'alloc_workqueue()' like macros accept a format specifier

Improve 'create_workqueue', 'create_freezable_workqueue' and
'create_singlethread_workqueue' so that they accept a format
specifier and a variable number of arguments.

This will put these macros more in line with 'alloc_ordered_workqueue' and
the underlying 'alloc_workqueue()' function.

This will also allow further code simplification.
