[PATCH 4.10 090/129] scsi: qedi: Fix possible memory leak in qedi_iscsi_update_conn()

[Greg Kroah-Hartman]

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

commit 8b9b22ba75907dcced88c815a5427ec0b4298aec upstream.

'conn_info' is malloced in qedi_iscsi_update_conn() and should be freed
before leaving from the error handling cases, otherwise it will cause
memory leak.

Fixes: ace7f46ba5fd ("scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.")
