Peter Ujfalusi f276f4e1b7 dmaengine: ti: k3-udma: Fix the TR initialization for prep_slave_sg

[ Upstream commit 33ebffa105 ]

The TR which needs to be initialized for the next sg entry is indexed by
tr_idx and not by the running i counter.

In case any sub element in the SG needs more than one TR, the code would
corrupt an already configured TR.
