fix: Update code to allow next-available for h/w reservation id in …

…metal_device module (#226)

Fixes #224 

A device that is not privisionable will fail when we try to provision on
it. Thus, removing the extra check of validation if a device is
provisionable or not allows us to pass `next-available` as the h/w
reservation id.
