dmaengine: ti: dma-crossbar: fix device leak on dra7x route allocation 



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

Note that commit 615a4bfc ("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.

Fixes: a074ae38 ("dmaengine: Add driver for TI DMA crossbar on DRA7x")
Fixes: 615a4bfc ("dmaengine: ti: Add missing put_device in ti_dra7_xbar_route_allocate")
