btrfs: tests: fix chunk map leak after failure to add it to the tree 



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.

Fixes: 7dc66abb ("btrfs: use a dedicated data structure for chunk maps")
