When building with Clang and CONFIG_BT_INTEL unset, the following error
occurs:
In file included from drivers/bluetooth/hci_ldisc.c:34:
drivers/bluetooth/btintel.h:188:2: error: void function
'btintel_reset_to_bootloader' should not return a value [-Wreturn-type]
return -EOPNOTSUPP;
^ ~~~~~~~~~~~
1 error generated.
Remove the unneeded return statement to fix this.
Fixes: b9a2562f49 ("Bluetooth: btusb: Trigger Intel FW download error recovery")
