wifi: ath12k: fix dma_free_coherent() pointer
commit bb97131fbf9b708dd9616ac2bdc793ad102b5c48 upstream.
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: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
