dmaengine: ti: k3-udma: fix device leak on udma lookup
commit 430f7803b69cd5e5694e5dfc884c6628870af36e 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: 1438cde8fe9c ("dmaengine: ti: k3-udma: add missing put_device() call in of_xudma_dev_get()")
