Don't hardcode unit 0 for the current device if we're loaded from an
EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.
We obviously want to do the same when we're booting over the network.
Maybe later.
Based on a patch (from memory) from: arun
