xfs: force swapext to a realtime file to use the file content exchange ioctl

Browse source

xfs_swap_extent_rmap does not use log items to track the overall
progress of an attempt to swap the extent mappings between two files.
If the system crashes in the middle of swapping a partially written
realtime extent, the mapping will be left in an inconsistent state
wherein a file can point to multiple extents on the rt volume.

The new file range exchange functionality handles this correctly, so all
callers must upgrade to that.
