dax_hmem (ab)uses a platform device to allow for a module to autoload in the presence of "Soft Reserved" resources. The dax_hmem driver had no dependencies on the "hmem_platform" device being a singleton until the recent "dax_hmem vs dax_cxl" takeover solution. Replace the layering violation of dax_hmem_work assuming that there will never be more than one "hmem_platform" device associated with a global work item with a dax_hmem local workqueue that can theoretically support any number of hmem_platform devices. Fixup the reference counting to only pin the device while it is live in the queue.
