btrfs: zoned: fix chunk map leak when loading block group zone info

Browse Source 
At btrfs_load_block_group_zone_info() we never drop a reference on the
chunk map we have looked up, therefore leaking a reference on it. So
add the missing btrfs_free_chunk_map() at the end of the function.

Fixes: 7dc66abb5a ("btrfs: use a dedicated data structure for chunk maps")
