Bluetooth: hci_ll: Fix download_firmware() return when __hci_cmd_sync fails
When __hci_cmd_sync() fails, download_firmware() should also fail, and
the same error value should be returned as PTR_ERR(skb).
Without this fix, download_firmware() will return a success when it actually
failed in __hci_cmd_sync().
