Bluetooth: controller: split: Fix PDU handling on terminate

Browse source 
Fix handling of Rx-ed PDU on termination, do not process
Rx-ed control PDUs and release the PDU buffer back to the
free pool.

Without this fix, Rx-ed control PDU was responded with a
Tx PDU, which did not get acknowledged or released.
