RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES

CVE-2024-53094

Description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES

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.
