Subject: [PATCH -next] Bluetooth: btusb: Remove return statement in btintel_reset_to_bootloader

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.
