[libvirt] [PATCH 1/3] LXC: avoid useless memory free in lxcContainerIdentifyCGroups

[Gao feng]

when lxcContainerIdentifyCGroups failed, lxcContainerSetupPivortRoot
and lxcContainerSetupExtraMounts will free the memory that allocated
in lxcContainerIdentifyCGroups.

So we need not call lxcContainerCGroupFree when
lxcContainerIdentifyCGroups failed.
