[libvirt] [PATCH 2/3] apparmor: no need to check security model

[Guannan Ren]

The security model has been set already when allocating and adding
virSecurityLabelDefPtr struct into virDomainDefPtr, so the value of
secdef->model is always non-null.
So error: security label already defined for VM is reported.
The patch is to remove the checking of its value in If condition clause
