Actually it already tests device for exclusive access (it is not only mount,
also for use in RAID, other device-mapper mappings etc), not sure why it
was detected so late. Maybe that debug would reveal it ;-)
Maybe it is racing with some automatic mount utility, dunno.

(The correct message should be "Cannot format device %s which is still in use."
but apparently it was not failing during this step.)
