core: ensure dhcp_manager exists before trying to unref it (bgo #626610)

Browse source 
If a new device wasn't supported, it gets destroyed by the
NMDevice constructor() method.  But in the constructor paths
the DHCP manager isn't created yet, and so we attempt to unref
a non-existent DHCP manager.  Usually just a harmless warning,
but apparently a crash sometimes.
