IB/iser: Remove redundant cmd_data_len calculation
This code was added before we had protection data length calculation (in iser_send_command), so we needed to calc the sg data length from the sg itself. This is not needed anymore. This patch does not change any functionality. Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Adir Lev <adirl@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
