Bluetooth: btqcomsmd: Fix skb double free corruption
[ Upstream commitpull/10/head67b8fbead4
] In case of hci send frame failure, skb is still owned by the caller (hci_core) and then should not be freed. This fixes crash on dragonboard-410c when sending SCO packet. skb is freed by both btqcomsmd and hci_core. Fixes:1511cc750c
