[PATCH] util: Fix segmentation fault when seclabel fails to allocate memory

[jcfaracco@xxxxxxxxx]

From: Julio Faracco <jcfaracco@xxxxxxxxx>

In function virSecurityDeviceLabelDefNew(), when libvirt fails to
allocate seclabel structure it returns a failure. This case is setting
seclabel as a NULL pointer and accessing its attribute below. This
commit fixes this wrong logic.
