[PATCH 2/2] net/mlx5: Simplify workqueue name creation

[Christophe JAILLET <christophe.jaillet@wanadoo.fr>]

There is no need to explicitly allocate, populate and free some memory
just to pass a workqueue name to 'create_singlethread_workqueue()'.

This macro can do all this for us, so keep the code simple.

A similar patch has also been sent. It was replacing the kmalloc/strcpy/
strcat with a kasprintf.
Updating 'create_singlethread_workqueue' gives an even more elegant solution.
