dmaengine: stm32: dmamux: fix device leak on route allocation
commit dd6e4943889fb354efa3f700e42739da9bddb6ef upstream.
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.
