dmaengine: mv_xor: kill tasklet on channel add error path
If request_irq() succeeds but a later step (self-test or device
registration) fails, the error path at err_free_irq frees the IRQ
but does not kill the tasklet. A previously scheduled tasklet can
still run after the channel is freed, accessing freed memory.
Add tasklet_kill() after free_irq() on the error path.
Fixes: ff7b04796d98 ("dmaengine: DMA engine driver for Marvell XOR engine")
