btrfs: use READ_ONCE() to read the chunk size from the data space_info
The chunk size of a space_info is always updated with WRITE_ONCE() (see
btrfs_update_space_info_chunk_size()), so when reading it in
calc_effective_data_chunk_size() we should use READ_ONCE() to prevent
load tearing. We are already using READ_ONCE() in every other function
that accesses the chunk size of a space_info.
