net: octeontx2: Restore default value for err

In nix_lf_setup there is a default value assigned to err in case an
error is detected. However this default value will be overwritten in the
for loop so that later code does not return an error code from the
function. Add a new assignment to restore err to the default error code.

This issue was found by Smatch.
