From: Baochen Qiang <quic_bqiang@xxxxxxxxxxx> [ Upstream commit 3d60041543189438cd1b03a1fa40ff6681c77970 ] Currently the resource allocated by crypto_alloc_shash() is not freed in case ath12k_peer_find() fails, resulting in memory leak. Add crypto_free_shash() to fix it. This is found during code review, compile tested only.
