Lv Yunlong 19d16a6897 crypto: qat - Fix a double free in adf_create_ring
[ Upstream commit f7cae626cabb3350b23722b78fe34dd7a615ca04 ]

In adf_create_ring, if the callee adf_init_ring() failed, the callee will
free the ring->base_addr by dma_free_coherent() and return -EFAULT. Then
adf_create_ring will goto err and the ring->base_addr will be freed again
in adf_cleanup_ring().

My patch sets ring->base_addr to NULL after the first freed to avoid the
double free.
