fix(iscsi): remove unneeded iscsi NOP-disable code

Commit 7374943 ("fix(iscsi): add support for the new iscsiadm
"no-wait" (-W) command") added some code to try to disable iscsi's
NOPs, since they are considered "bad" for an iscsi root disc,
but that code doesn't work because the session is already established
at this point. Open-iscsi will change so that it automatically
disables NOPs for the root disc, so this code can just go away.
