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"
