iscsi: replace incorrect off_t with ptrdiff_t 



This code calculates the difference between two pointers and then stores
it in an off_t, which is intended for file offsets.

In this particular case, the offset will never be large enough to
overflow off_t, but use the correct ptrdiff_t type anyway.
