[libvirt] [PATCH 2/2] util: moving 'type' argument to avoid issues with mount() syscall.

[Julio Faracco]

This commit fixes a mount call inside virgroup.c file. The NULL value
into 'type' argument is causing a memory issue. See commit 794b576c2b
for more details. The best approach to fix it is moving NULL to "none"
filesytem.
