[PATCH v1 4/4] dmaengine: consistently return string literal from switch-case

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

There is no need to have 'break;' statement in the default case followed by
return certain string literal when all other cases have returned the string
literals. So, refactor it accordingly.
