btrfs: fix a leaked chunk map issue in read_one_chunk()
commit 35d99c68af40a8ca175babc5a89ef7e2226fb3ca upstream.
Add btrfs_free_chunk_map() to free the memory allocated
by btrfs_alloc_chunk_map() if btrfs_add_chunk_map() fails.
Fixes: 7dc66abb5a47 ("btrfs: use a dedicated data structure for chunk maps")
