Sungwoo Kim 75767213f3 Bluetooth: L2CAP: Add missing checks for invalid DCID 
When receiving a connect response we should make sure that the DCID is
within the valid range and that we don't already have another channel
allocated for the same DCID.
Missing checks may violate the specification (BLUETOOTH CORE SPECIFICATION
Version 5.4 | Vol 3, Part A, Page 1046).

Fixes: 40624183c2 ("Bluetooth: L2CAP: Add missing checks for invalid LE DCID")
