Peter Ujfalusi 9d9c2884da dmaengine: ti-dma-crossbar: Fix possible race condition with dma_inuse
commit 2ccb4837c9 upstream.

When looking for unused xbar_out lane we should also protect the set_bit()
call with the same mutex to protect against concurrent threads picking the
same ID.

Fixes: ec9bfa1e1a ("dmaengine: ti-dma-crossbar: dra7: Use bitops instead of idr")
