drivers: dma: stm32: DMA V1 channel direction

Browse source 
The channel direction for a V1 DMA is not allowed to be memory to memory
and there is a check in place for this. However, the check is being
performed on the stream prior to actually configuring the stream. This
results in the check always failing regardless of the channel direction.

The check has been modified to be performed on the incoming
configuration.
