Sanity check section size in bfd_init_section_compress_status

[Alan Modra]

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.
