dmaengine: stm32-mdma: memset stm32_mdma_chan_config struct before using it
New bool m2m_hw has been added at the end of stm32_mdma_chan_config struct
to support the STM32 DMA MDMA chaining.
m2m_hw is set true in stm32_mdma_slave_config() if peripheral_size is set,
but m2m_hw is never initialized false.
To ensure this case, and any further new update of the structure, memset it
to 0 before using it.
