util/ifdtool: Fix invalid pointer dereference

When calculating the GPR0 protection range, currently the offsets of
"CSE data partition offset" and FPT are not checked. Invalid pointer
dereference may lead to segmentation fault.

Ensure the offset is within the image size before accessing the pointer.
