[PATCH] dmaengine: ti: k3-udma: Fix a resource leak in an error handling path

[Christophe JAILLET]

In 'dma_pool_create()', we return -ENOMEM, but don't release the resources
already allocated, as in all the other error handling paths.

Go to 'err_res_free' instead of returning directly.

Fixes: 017794739702 ("dmaengine: ti: k3-udma: Initial support for K3 BCDMA")

This patch is not even compile tested.
I don't have the needed configuration.
