serial: imx: remove a redundant check
cpp_check reports
drivers/tty/serial/imx.c:1207:15: style: Condition 'r_bytes>0' is always true [knownConditionTrueFalse]
if (r_bytes > 0) {
r_byte is set to
r_bytes = rx_ring->head - rx_ring->tail;
The head - tail calculation is also done by the earlier check
if (rx_ring->head <= sg_dma_len(sgl) &&
rx_ring->head > rx_ring->tail) {
so r_bytes will always be > 0, so the second check is not needed.
