soc: ti: k3-navss-ringacc: Do not use uninitialised variable

In k3_nav_ringacc_probe_dt there can be no error code returned from
dev_read_u32_default so ret is not assigned to and should not be used.
Remove the use of ret from the dev_err call as it is unitialised.

This issue was found by Smatch.
