Bluetooth: btintel: Fix missing free skb in btintel_setup_combined() 

[ Upstream commit cee50ce899 ]

skb allocated by __hci_cmd_sync would not be used whether in checking
for supported iBT hardware variants or after, we should free it in all
error branches, this patch makes the case read version failed or default
error case free skb before return.

Fixes: c86c7285bb ("Bluetooth: btintel: Fix the legacy bootloader returns tlv based version")
Fixes: 019a1caa7f ("Bluetooth: btintel: Refactoring setup routine for bootloader devices")
