dmaengine: mv_xor_v2: kill the tasklets upon exit
The mv_xor_v2 driver uses a tasklet, initialized during the probe() routine. However, it forgets to cleanup the tasklet using tasklet_kill() function during the remove() routine, which this patch fixes. This prevents the tasklet from potentially running after the module has been removed.
