target/pscsi: Reject cross page boundary case in pscsi_map_sg
We can only have one page of data in each sg element, so we can not cross a page boundary. Fail this case. The 'while (len > 0 && data_len > 0) {}' loop is not necessary. The loop can only be executed once. Signed-off-by: Asias He <asias@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
