[PATCH] dmaengine: ti: k3-udma: Use common error handling code in udma_prep_slave_sg_pkt()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 10 Jun 2026 21:43:12 +0200

Use an additional label so that a bit of exception handling can be better
reused at the end of an if branch.

This issue was detected by using the Coccinelle software.
