selftests: firmware: add empty string and async tests
Now that we've added a 'trigger_async_request' knob to test the request_firmware_nowait() API, let's use it. Also add tests for the empty ("") string, since there have been a couple errors in that handling already. Since we now have real ways that the sysfs write might fail, let's add the appropriate check on the 'echo' lines too.
