qemu: restore persistent mac address support

Browse Source 
If the state dir is preserved then the VM should come up with the same mac
address on subsequent reboots.

Fixes regression in #2498.

Rather than fixing the typo in the associated comments just remove them since
they don't really convey any useful information.
