The one which actually saves the data is data_list.data.d.d_buf, so check it
before free rawdata_base.
This can fix a segmentation fault when prelink libqb_1.0.3:
prelink: /usr/lib/libqb.so.0.18.2: Symbol section index outside of section
numbers
The segmentation fault happens when prelink call elf_end().
