Description: Per Bluetooth Core Specification 6.2:
The CS procedure counter CSProcCount shall be incremented by one after every successful completion of the CS Start procedure, except for the occurrence that immediately follows the completion of the CS Security Start procedure.
Currently, the device may reply with an LL_REJECT_EXT_IND PDU, which will cancel the Start procedure sequence. In such case, the ProcedureCounter shall not be incremented, but the current implementation does not handle this correctly. This causes incorrect synchronization in Channel Sounding (CS) procedures when reject packets are sent or received.
