Gavin Shan 7c09f4281c drivers/base/memory: Fix comments for phys_index_show() ...

According to 'admin-guide/mm/memory-hotplug.rst', the memory block ID,
instead of the section index, is shown by '/sys/devices/system/memory/
memoryX/phys_index'.

Fix the comments to match with 'admin-guide/mm/memory-hotplug.rst'.
Besides, use the existing helper memory_block_id() to convert the section
index to the memory block index.

No functional change intended.
