Bluetooth: controller: ull/lll: Fix pin or key missing response

Fix the missing reset of Encryption Procedure state when the
peripheral responded with error reason as pin or key missing
which otherwise caused connection disconnection on next
reception of data or control packet.

Relates to #15570, and #15727.
