i3c: master: dw: remove dead code from dw_i3c_master_*_xfers()
Detected by CoverityScan (Event result_independent_of_operands): "(i3c_xfers + i).len > 65536" is always false regardless of the values of its operands. This occurs as the logical operand of "if" "(i2c_xfers + i).len > 65536" is always false regardless of the values of its operands. This occurs as the logical operand of "if" Signed-off-by: Vitor Soares <vitor.soares@synopsys.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com>
