Dan Williams a455aa72f7 device-dax/kmem: fix resource release 
The conversion to request_mem_region() is broken because it assumes that
the range is marked busy prior to release.  However, due to the way that
the kmem driver manipulates the IORESOURCE_BUSY flag (clears it to let
{add,remove}_memory() handle busy) it requires a manual release_resource()
to perform cleanup.

Given that the actual 'struct resource *' needs to be recalled, not just
the range, add that tracking to the kmem driver-data.

Fixes: 0513bd5bb1 ("device-dax/kmem: replace release_resource() with release_mem_region()")
