scsi: libcxgbi: Remove an unused field in struct cxgbi_device

Usage of .dev_ddp_cleanup() in libcxgbi was removed by commit 5999299
("cxgb3i,cxgb4i,libcxgbi: remove iSCSI DDP support") on 2016-07.

.csk_rx_pdu_ready() and debugfs_root have apparently never been used since
introduction by commit 9ba682f ("[SCSI] libcxgbi: common library for
cxgb3i and cxgb4i")

Remove the now unused function pointer from struct cxgbi_device.
