Bluetooth: controller: Fix supervision timeout countdown

Browse source 
Add missing supervision timeout countdown initiation on CRC
error.

This fixes TP/CON/ADV/BI-01-C [Connection Supervision
Timeout during Fail Connection Setup] and TP/CON/INI/BI-02-C
[Slave Packets Invalid CRC] in LL.TS.5.0.0.
