BQR: Fix for the issue that Bluetooth keeps on crashing if the

controller firmware does not support the BQR feature.

Considering for the Treble case, it might upgrade the system image
only and the BQR feature will be enabled on a device whose Bluetooth
controller firmware does not support the BQR feature. The change is
not to crash the system if the controller firmware does not handle the
BQR VSC.

Bug: 129037162
Test: Enabled the BQR feature on the device whose Bluetooth controller
firmware does not support the BQR feature. The Bluetooth can be turned
on and works normally.
