dmaengine: stm32-mdma: fix chan initialization in stm32_mdma_irq_handler()
[ Upstream commit da3b8ddb464bd49b6248d00ca888ad751c9e44fd ]
The parameter to pass back to the handler function when irq has been
requested is a struct stm32_mdma_device pointer, not a struct
stm32_mdma_chan pointer.
Even if chan is reinit later in the function, remove this wrong
initialization.
