As Bagman says, it's normal and expected with Maple necks, regardless of source. There just isn't a better way to do it unless the manufacturer does neck setup before shipping, which is sadly more rare than it should be for what a lot of them charge.
But, lacquer and poly both chip off the frets pretty easily as neither sticks to metal very well without help. Get yourself a pack of utility blades and a generous mittenful of patience and you can clean 'em up well enough to play, which will finish them off.
Or, you could send the neck off to somebody who will level, crown, dress and polish the frets for you. Then you don't have to worry about it all. Maybe even get some threaded inserts installed. Hmmm... who could that be?
