[PATCH tty/serial 4/5] tty: serial: fsl_lpuart: remove sg_set_buf() for sport->rx_sgl

[fugang.duan@xxxxxxx]

From: Fugang Duan <fugang.duan@xxxxxxx>

Since .sg_init_one() already set sg entry page like below code.
	sg_init_one()
		sg_init_table(sg, 1);
		sg_set_buf(sg, buf, buflen);

So it should not set sg entry page again, remove the redundant code.
