This\nleads invalid pointer dereference during connection teardown.\n\nFix by setting iscsi_conn->dd_data only if memory is actually allocated.\n\nPanic trace:\n------------\n iser: iser_create_fastreg_desc: Failed to allocate ib_fast_reg_mr err=-12\n iser: iser_alloc_rx_descriptors: failed allocating rx descriptors / data buffers\n BUG: unable to handle page fault for address: fffffffffffffff8\n RIP: 0010:swake_up_locked.part.5+0xa/0x40\n Call Trace:\n  complete+0x31/0x40\n  iscsi_iser_conn_stop+0x88/0xb0 [ib_iser]\n  iscsi_stop_conn+0x66/0xc0 [scsi_transport_iscsi]\n  iscsi_if_stop_conn+0x14a/0x150 [scsi_transport_iscsi]\n  iscsi_if_rx+0x1135/0x1834 [scsi_transport_iscsi]\n  ? netlink_lookup+0x12f/0x1b0\n  ? netlink_deliver_tap+0x2c/0x200\n  netlink_unicast+0x1ab/0x280\n  netlink_sendmsg+0x257/0x4f0\n  ? _copy_from_user+0x29/0x60\n  sock_sendmsg+0x5f/0x70",
