When compiling with gcc 4.6, some code in fw_cfg.c complains that fop_ret
is assigned but not used (which is true). However, it looks like the
meaningless assignments to fop_ret were done to suppress other gcc warnings
due to the fact that fread() is labelled as warn_unused_result in glibc.
This patch avoids both errors, by actually checking the fread() result code
and dropping out with an error message if it fails.
