dmaengine: stm32: dmamux: fix device leak on route allocation
Make sure to drop the reference taken when looking up the DMA mux
platform device during route allocation.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.
Analysis and contextual insights are available on OpenCVE Cloud.
No vendor fix or workaround currently provided.
