Make sure to drop the reference taken when looking up the crossbar platform device during dra7x route allocation.

Note that commit 615a4bfc426e ("dmaengine: ti: Add missing put_device in ti_dra7_xbar_route_allocate") fixed the leak in the error paths but the reference is still leaking on successful allocation.
