Target/iser: Fix a wrong dereference in case discovery session is over iser
commit e0546fc1ba66c90cb38a5764357366267d3e58e4 upstream. In case the discovery session is carried over iser, we can't access the assumed network portal since the default portal is used. In this case we don't really need to allocate the fastreg pool, just prepare to the text pdu that will follow.
