[LU-16445] Make nodemap root squash independent of map_mode

Description

When a nodemap has map_mode=projid, only projid is mapped. So even if the admin property is set to 0, user root (0:0) will remain as-is.

I will push a patch to change this behavior and have root user squashed if admin is set to 0, independently of the map_mode.
