Bluetooth: btqcomsmd: Fix skb double free corruption
[ Upstream commit 67b8fbead4685b36d290a0ef91c6ddffc4920ec9 ]
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: 1511cc750c3d ("Bluetooth: Introduce Qualcomm WCNSS SMD based HCI driver")
