It has been observed that fit_check_format() will fail when passed a corrupt FIT image. This was tracked down to _fdt_string_eq(): return (strlen(p) == len) && (memcmp(p, s, len) == 0);

In the case of a corrupt FIT image one can't depend on 'p' being NULL terminated. I changed it to use strnlen() to fix the issue.
