    mem(4): Improve ioctl section formatting
    
    Add the missing .El which fixes the indentation of the memory range
    definitions and operation. Add subsection headings to further clarify
    this section. Do the same for the RETURN VALUES section, and mention
    explicitly that MEM_EXTRACT_PADDR always returns zero.
