DDF: ensure dl->devname is freed when processing a 'delete device' update.

As this code runs in 'monitor' it cannot just free memory,
it must add it to a list for 'manager' to free.
Fortunate update->space_list exists for just this purpose.
dl->devname might be small, so put it in update->space and
put dl in update->space_list.
