This is tangled in another patch that enables 64-bit vdev-maps,
but I will rebase and post it shortly.

Another question in the related code:  For monitor devices, we
are using bit - 1 for the monitor device ID, but we do not subtract
one when creating normal stations.  Is this on purpose?

And, instead of checking for bit == 0, why not check for
zero map before we even try the ffs call?  That should work
for __ffs64 as well, which is what I need for lots of vdevs...

Thanks,
Ben
