[stgt] [PATCH 3/3] Fix segfault on exit

[Andy Grover]

If iser_ib_init fails (due to no RDMA-capable hw, which is ok) and
iser_send_nop is 1, then tgtd will segfault on exit, trying to remove
the work item that was never initialized or added.

See https://bugzilla.redhat.com/show_bug.cgi?id=712807 for more info.
