These fake controllers cannot be initialized because they return a smaller 
report than expected for READ_VOICE_SETTING and READ_PAGE_SCAN_TYPE.

This affects fake controllers reusing the 0A12:0001 VID/PID.

Fixes: c8992cffbe74 ("Bluetooth: hci_event: Use of a function table to handle Command Complete")

Changes in v4:
- Check commands for READ_VOICE_SETTING.
- Disable SCO support if READ_VOICE_SETTING is unsupported/broken. 

Changes in v3:
- Correct the fixes commit. 

Changes in v2:
