iscsi-scst: Suppress put_page_callback patch warnings

The put_page_callback patch only improves performance on single
socket systems but not on systems with multiple CPU sockets.
Since this message is confusing to SCST users, do not print a
warning if the put_page_callback patch has not been applied.
