[Devel] [PATCH RH7 01/14] mount: rename do_set_group to do_set_group_old

[Pavel Tikhomirov]

We have a VZ-only feature to copy mount sharing between mounts via mount
syscall, to be able to handle mount restore in CRIU u15-u19 efficiently.

In mainstream there is now similar feature through move_mount syscall.

To support both old criu and new criu, which uses ms API, at the same
time let's fix name collision and leave both variants for now, several
updates later we can drop old mount syscall based API.
