Johan Hovold ec6df35c66 dmaengine: ti: k3-udma: fix device leak on udma lookup ...

commit 430f7803b6 upstream.

Make sure to drop the reference taken when looking up the UDMA platform
device.

Note that holding a reference to a platform device does not prevent its
driver data from going away so there is no point in keeping the
reference after the lookup helper returns.

Fixes: d702419134 ("dmaengine: ti: k3-udma: Add glue layer for non DMAengine users")
Fixes: 1438cde8fe ("dmaengine: ti: k3-udma: add missing put_device() call in of_xudma_dev_get()")
