drivers/base/memory.c: clean up relics in function parameters
The input parameter 'phys_index' of memory_block_action() is actually the section number, but not the phys_index of memory_block. This is a relic from the past when one memory block could only contain one section. Rename it to start_section_nr. And also in remove_memory_section(), the 'node_id' and 'phys_device' arguments are not used by anyone. Remove them.
