PR24898, An out-of-bounds read occured in display_data
Given 32-bit pointers and a 64-bit bfd_size_type, it is relatively
easy to construct a value of augmentation_data_len (eg. 0x100000000)
that won't fail pointer checks but will print without bounds.
PR 24898
* dwarf.c (display_debug_frames): Use the read_cie check and error
for augmentation data length.
