next: arm64: defconfig: gcc-8: drivers/bluetooth/hci_qca.c:2501:2: error: label at end of compound statement

[Naresh Kamboju]

The arm64 defconfig gcc-8 build failed [1] due to these warnings / errors on the
Linux next-20230711 tag. But the gcc-13 builds pass.

LKFT is testing older toolchain support till gcc-8.

The following recent changes cause this failure.
a887c8dede8e1 Bluetooth: hci_qca: schedule a devm action for disabling the clock

Build errors with gcc-8:
-----------
drivers/bluetooth/hci_qca.c: In function 'qca_serdev_remove':
