Miklos Szeredi 4ae404afd9 fuse: clean up device cloning ...

- fuse_mutex is not needed for device cloning, because fuse_dev_install()
   uses cmpxcg() to set fud->fc, which prevents races between clone/mount
   or clone/clone.  This makes the logic simpler

 - Drop fc->dev_count.  This is only used to check in release if the device
   is the last clone, but checking list_empty(&fc->devices) is equivalent
   after removing the released device from the list.  Removing the fuse_dev
   before calling fuse_abort_conn() is okay, since the processing and io
   lists are now empty for this device.
