commit 009ca358486ded9b4822eddb924009b6848d7271 upstream.
If we fail to add the chunk map to the fs mapping tree we exit test_rmap_block() without freeing the chunk map. Fix this by adding a call to btrfs_free_chunk_map() before exiting the test function if the call to btrfs_add_chunk_map() failed.
