wifi: ath10k: fix dma_free_coherent() pointer 



dma_alloc_coherent() allocates a DMA mapped buffer and stores the
addresses in XXX_unaligned fields.  Those should be reused when freeing
the buffer rather than the aligned addresses.

Fixes: 2a1e1ad3 ("ath10k: Add support for 64 bit ce descriptor")
