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.

util: make allocation functions abort on OOM
libvirt's allocation functions never fail.
This change was made to allow usage of GLib allocation functions, which
also abort on OOM.

So everything inside this if is dead code waiting to be cleaned up.
See:
https://libvirt.org/hacking.html#glib
for the GLib equivalents of functions for allocation.
