Modify the netfront driver so it can successfully attach to

PV devices with the ioemu attribute set.

sys/dev/xen/netfront/netfront.c:
	o If a mac address for the interface cannot be found
	  in the front-side XenStore tree, look for an entry
	  in the back-side tree.  With ioemu devices, the
	  emulator does not populate the front side tree and
	  neither does Xend.
	o Return an error rather than panic when an attach
	  attempt fails.
