iser-target: Fix error path in isert_create_pi_ctx()
We don't assign pi_ctx to desc->pi_ctx until we're certain to succeed in the function. That means the cleanup path should use the local pi_ctx variable, not desc->pi_ctx. This was detected by Coverity (CID 1260062). Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
