While running ISER over SIW, the initiator machine encounters a warning
from skb_splice_from_iter() indicating that a slab page is being used in
send_page. To address this, it is better to add a sendpage_ok() check
within the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag
should be disabled before entering the network stack.

A similar issue has been discussed for NVMe in this thread:

As opposed to open-code, using the ERR_CAST macro clearly indicates that
this is a pointer to an error value and a type conversion was performed.

Toggling link while running NVME-oF over siw hits a kernel panic
due to race condition within siw_handler and ib_destroy_qp().
The IB_EVENT_PORT_ERR event can alone handle destroying qps.
therefore remove unwanted processing in siw.
