FLAC's delete() is broken

[Bobloblaw09274237009]

Looking at the code to FLAC delete():

from mutagen.flac import FLAC

If you do:
FLAC().delete(fileobj)
this silently fails because because self.tags is always None.

This is confusing beccause in ID3 this behavior works as expected and the tags are deleted from fileobj:
ID3().delete(fileobj)

The documentation is incorrect as it says FLAC's delete() takes *args,**kwargs which it does not.

Additionally, I get an infinite loop when I try to call it:
myflac = open('test.flac','rb').read()
sio = StringIO(); sio.write(myflac); sio.seek(0)
sio2 = StringIO(); sio2.write(sio.read()); sio.seek(0); sio2.seek(0)
fl = FLAC(sio)
fl.delete(sio2); # Infinite loop while writing out to sio2

Thanks.

from mutagen.flac import delete; delete(..) should work in the meantime.
