Use vmem_free() in dfl_free() and add dfl_alloc()

This change was lost, somehow, in e5f9a9a.  Since the arrays can be
rather large, they need to be allocated with vmem_zalloc() via dfl_alloc()
and freed with vmem_free() via dfl_free().

The new dfl_alloc() function should be used to allocate object of type
dkioc_free_list_t in order that they're allocated from vmem.
