Subject: btrfs: btrfs_relocate_chunk pass extent_root to btrfs_end_transaction

In btrfs_relocate_chunk, we get a transaction handle via
btrfs_start_trans_remove_block_group, which starts the transaction
using the extent root.  When we call btrfs_end_transaction, we're calling
it using the chunk root.
