internal: remove unused variable

The variable 'ret' is unused when compiling on big-endian architecture.

This produces an "unused variable" message, which might be treated as error
if -Werror was passed to compiler.

With this patch I was able to compile flashrom cleanly on ppc and ppc64:

Corresponding to flashrom svn r1180.
