scsi: libiscsi: use sendpage_ok() in iscsi_tcp_segment_map()
In iscsci driver, iscsi_tcp_segment_map() uses the following code to
check whether the page should or not be handled by sendpage:
if (!recv && page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg)))
The "page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg)" part is to
make sure the page can be sent to network layer's zero copy path. This
part is exactly what sendpage_ok() does.
This patch uses use sendpage_ok() in iscsi_tcp_segment_map() to replace
the original open coded checks.
