memory hotplug: release memory regions in PAGES_PER_SECTION chunks

During hotplug memory remove, memory regions should be released on a
PAGES_PER_SECTION size chunks.  This mirrors the code in add_memory where
resources are requested on a PAGES_PER_SECTION size.

Attempting to release the entire memory region fails because there is not
a single resource for the total number of pages being removed.  Instead
the resources for the pages are split in PAGES_PER_SECTION size chunks as
requested during memory add.
