[PATCH] mm: memory_hotplug: Remove unnecesary check from register_page_bootmem_info_section()

[Oscar Salvador <osalvador@techadventures.net>]

When we call register_page_bootmem_info_section() having CONFIG_SPARSEMEM_VMEMMAP enabled,
we check if the pfn is valid.
This check is redundant as we already checked this in register_page_bootmem_info_node()
before calling register_page_bootmem_info_section(), so let's get rid of it.
