ID:335 - Check return value of fseek(), prevent segfault

Browse Source 
Commit adds a check as a workaround for segfault reported in ID:335. However,
the proper fix is to rewrite parts of lib/ipmi_hpmfwupg.c not to put whole
firmware image into memory. Also, MD5 checksum part needs to be rewritten,
because it won't work for large firmware images.
