Btrfs: delay iput when deleting a block group

I kept getting warnings from evict because we were calling
btrfs_start_transaction() with a transaction already started when doing a
balance.  This is because we remove a block group which requires a transaction,
and the put the last reference on the cache inode.  Instead of doing this we
need to delay the iput so it is done not within a transaction having started.
This gets rid of our warnings.  Thanks,
