Message:

Avoid releasing DMA memory twice

When hda_corb_init or hda_rirb_init fail, they attempt to deallocate the
allocated DMA memory, but don't set the corb_virt or rirb_virt pointers
to NULL so that hda_ctl_init later calls hda_corb_fini and
hda_rirb_fini, where these pointers are found non-NULL and so the DMA
memory is deallocated for the second time.
