soc: fsl: cpm1: qmc: Fix rx channel reset
The qmc_chan_reset_rx() set the is_rx_stopped flag. This leads to an
inconsistent state in the following sequence.
qmc_chan_stop()
qmc_chan_reset()
Indeed, after the qmc_chan_reset() call, the channel must still be
stopped. Only a qmc_chan_start() call can move the channel from stopped
state to started state.
Fix the issue removing the is_rx_stopped flag setting from
qmc_chan_reset()
