Bluetooth: controller: Fix missing CPR procedure reset

Browse source 
When connection parameter request procedure was responded
by master role with Unsupported Link Layer Parameter Value,
a missing reset of the connection parameter request
procedure state caused next connection parameter request to
be incorrectly responded with same procedure collision
extended reject ind PDU. This caused an eventual connection
disconnection with reason LMP response timeout. This is now
fixed by reseting the state correctly.
