[PATCH v2 4/6] ASoC: Intel: Skylake: Unmap the address last

[Vinod Koul <vinod.koul@intel.com>]

In Skylake destructor we unmap the hardware address and then free
links and streams. The stream free accesses hardware to write to
registers and predictably causes oops.

So change the order and unmap last in destructor.
