io_uring: add IORING_OP_URING_CMD128 to opcode checks
io_should_commit(), io_uring_classic_poll(), and io_do_iopoll() compare struct io_kiocb's opcode against IORING_OP_URING_CMD to implement special treatment for uring_cmds. The recently added opcode IORING_OP_URING_CMD128 is meant to be equivalent to IORING_OP_URING_CMD, so treat it the same way in these functions.
