scripts: fixed missing argument in parse_from_attribute call.

In size_report script, if the DWARF section of ELF file contains both
debug_loc and a debug_loclists sections, LocationListsPair class is
used to track locations. In that case, parse_from_attribute was missing
one argument which was causing the script to fail.
