xfs: enable fsmap reporting for internal RT devices

File system with internal RT devices are a bit odd in that we need
to report AGs and RGs.  To make this happen use separate synthetic
fmr_device values for the different sections instead of the dev_t
mapping used by other XFS configurations.

The data device is reported as file system metadata before the
start of the RGs for the synthetic RT fmr_device.
