btrfs: don't use set/get token for single assignment in overwrite_item

Browse source 
The set/get token is supposed to cache the last page that was accessed
so it speeds up subsequential access to the eb. It does not make sense
to use that for just one change, which is the case of inode size in
overwrite_item.
