[PATCH] net/mlx5: Use kasprintf instead of hand-writing it

[Christophe JAILLET]

'kasprintf()' can replace a kmalloc/strcpy/strcat sequence.
It is less verbose and avoid the use of a magic number (64).

Anyway, the underlying 'alloc_workqueue()' would only keep the 24 first
chars (i.e. sizeof(struct workqueue_struct->name) = WQ_NAME_LEN).
