[PATCH 3/5] worker: use variable already set at beginning of loops

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

This is mainly question of style.
Instead of repeating same conversion use the variable we set at the
beginning of the function.
Note also that I used same name to make the two functions more
similar.
