ddi_dma_free_handle() destroys the DMA handle pointed to by handle.

results. Note that ddi_dma_unbind_handle(9F) must be called prior to
ddi_dma_free_handle() to free any resources the system may be caching
on the handle.
ddi_dma_free_handle() can be called from user, kernel, or interrupt
context.

context.
