Fix a bug in _stats_set_aux() that causes bogus data to appear
in the 'userdata' field of stats reports when previously grouped
regions are ungrouped:
/var/tmp/File With Spaces: Created new group with 1 region(s) as group ID 0.
Removed group ID 0 on fedora-root
Name GrpID RgID ObjType RgStart RgSize #Areas ArSize ProgID UserData
fedora-root - 0 region 6.39g 100.00m 1 100.00m dmstats #-
^^
This is the aux_data separator character followed by empty user data.
The _stats_set_aux() function should only emit the separator if
there is a valid group descriptor for the region.
