LE Audio: Update BASS / Scan Delegator to v.1.0.1

[Thalley]

Is your enhancement proposal related to a problem? Please describe.
The Broadcast Audio Scan Service v.1.0.1 has been released and require a few changes in Zephyr to be compliant.

Describe the solution you'd like
Specifically erratum 26529 needs to be implemented, which changes how the bad broadcast code is handled.

The change required is that instead of copying the bad broadcast code to the bad broadcast code field, the spec now requires setting the bad broadcast code field to 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF (all octets set to 0xFF).

Describe alternatives you've considered
N/A
