[ Upstream commit48b19b79cf] The validity of sock should be checked before assignment to avoid incorrect values. Commit57569c37f0("scsi: iscsi: iscsi_tcp: Fix null-ptr-deref while calling getpeername()") introduced this change which may lead to inconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en. Fix the issue by moving the position of the assignment.
