Btrfs: let the user know space caching is enabled
If you mount -o space_cache, the option will be persistent across mounts, but to make sure the user knows that they did this, emit a message telling them if they didn't mount with -o space_cache but the feature is still used. Signed-off-by: Josef Bacik <josef@redhat.com>
