dmaengine: mv_xor_v2: kill the tasklets upon exit 

[ Upstream commit 8bbafed8dd ]

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.

Fixes: 19a340b1a8 ("dmaengine: mv_xor_v2: new driver")
