target/iscsi: Use proper SGL accessors for digest computation
Current implementation assumes that all the buffers of an IO are linked
with a single SG list, which is OK because target-core is only allocating
a contigious scatterlist region. However, this assumption is wrong for
se_cmd descriptors that want to use chaining across multiple SGL regions.
Fix this up by using proper SGL accessors for digest payload computation.
