net: dsa: return success if there was nothing to do
Clang static analysis reports this representative issue dsa.c:486:2: warning: Undefined or garbage value returned to caller return err; ^~~~~~~~~~ err is only set in the loop. If the loop is empty, garbage will be returned. So initialize err to 0 to handle this noop case.
