fix(bt/bluedroid): fix ACL reassembly dropping valid continuation fragments (v6.0)

Jin Cheng 03c7e87202 fix(bt/bluedroid): moved L2CAP length check into start packets only 2026-04-08 20:39:55 +08:00
Jon Gilmore 051e0e671c fix(bt/bluedroid): fix ACL reassembly dropping valid continuation fragments 
The minimum length check in `reassemble_and_dispatch()` applied the START packet minimum (`HCI_ACL_PREAMBLE_SIZE + L2CAP_LENGTH_SIZE` = 8 bytes) to **all** ACL packets, including continuation fragments. Continuation fragments only carry the 4-byte ACL preamble (handle + length) with no L2CAP header, so small but valid continuations (5-7 bytes) were incorrectly rejected as "too short."

This caused the first L2CAP PDU in a rapid burst of BLE GATT indications to be silently dropped. The partial reassembly was orphaned, then discarded when the next indication's START fragment arrived, producing:

```
E BT_HCI: ACL packet too short (len=5)
W BT_HCI: reassemble_and_dispatch found unfinished packet for handle with start packet. Dropping old.
```

Parse the ACL preamble first (requires only 4 bytes) to determine the boundary flag, then apply the L2CAP length check only to START packets. Continuation packets are now accepted with the correct minimum of `HCI_ACL_PREAMBLE_SIZE` (4 bytes).

- ESP32-S3 connected to a BLE peripheral that fragments indications at 40 bytes per L2CAP PDU
- Peripheral sends 8+ indications within ~200ms (burst of state changes)
- The final continuation fragment of the first indication is small (5-6 bytes after type stripping)
- 100% reproducible on every burst; confirmed on ESP-IDF 5.5.3, 5.5.4, and 6.0.0

Verified on ESP32-S3 with a Sub-Zero wall oven (SO3050PESP, firmware 8.5):
- **Before fix:** First indication in every burst lost (ACL reassembly failure)
- **After fix:** All indications in burst delivered correctly, including when the final continuation fragment is 5-6 bytes
