mm/hotplug: kill is_dev_zone() usage in __remove_pages()

Browse Source 
commit 96da4350000973ef9310a10d077d65bbc017f093 upstream.

-- snip --

Minor conflict, keep the altmap check.

-- snip --

The zone type check was a leftover from the cleanup that plumbed altmap
through the memory hotplug path, i.e.  commit da024512a1fa "mm: pass the
vmem_altmap to arch_remove_memory and __remove_pages".
