dmaengine: stm32-mdma: abort resume if no ongoing transfer
chan->desc can be null, if transfer is terminated when resume is called,
leading to a NULL pointer when retrieving the hwdesc.
To avoid this case, check that chan->desc is not null and channel is
disabled (transfer previously paused or terminated).
Fixes: a4ffb13c8946 ("dmaengine: Add STM32 MDMA driver")
