Instead of breaking the lines up like this you should factor the code
out or find some other way to reduce the indentation.

Something needs to stop the queue, right? Otherwise the stack will 
send the frame right back to the driver.

This helper has a single caller, just put the two lines of code directly
there. And use napi_complete_done(), please.
