Dan Williams caed0243f5 bluetooth: fix crash creating device 
Due to the hardware address changes in 77dda53b (danw/hwlen) creating
a new Bluetooth device was crashing.  The changes there assumed that the
NMDeviceBt's hardware address should only be valid when we were connected
to the device, but that's not quite true.  Since we already know the remote
device's Bluetooth hardware address, we already know the hardware address
for the NMDeviceBt as well.
