btrfs: check folio mapping after unlock in put_file_data()
commit 0fba7be1ca6df2881e68386e5575fe096f33c4ca upstream.
When we call btrfs_read_folio() we get an unlocked folio, so it is possible
for a different thread to concurrently modify folio->mapping. We must
check that this hasn't happened once we do have the lock.
