Alain Volmat 6c4a91f9bb dmaengine: stm32-mdma: correct desc prep when channel running 
commit 03f25d53b1 upstream.

In case of the prep descriptor while the channel is already running, the
CCR register value stored into the channel could already have its EN bit
set.  This would lead to a bad transfer since, at start transfer time,
enabling the channel while other registers aren't yet properly set.
To avoid this, ensure to mask the CCR_EN bit when storing the ccr value
into the mdma channel structure.

Fixes: a4ffb13c89 ("dmaengine: Add STM32 MDMA driver")
