Sanity check section size in bfd_init_section_compress_status
This function doesn't just initialise for compression, it actually
compresses. This patch sanity checks section size before allocating
buffers for the uncompressed contents.
* compress.c (bfd_init_section_compress_status): Sanity check
section size.
