Refactor DRB release handling to use actual DRB IDs

Browse Source 
- Replace simple counter-based DRB ID assignment with actual DRB ID lookup
- Add nested loop to iterate through DRBs for each PDU session to be release
- Improve logic flow with early continue for non-matching PDU sessions

This ensures DRB release list contains correct DRB IDs that correspond to actual DRB entities
