BNEP: Fix OOB access in bnep_data_ind

* Stop reading the L2CAP packet if packet length is 0
* Process the buffer for BNEP_EXTENSION_CONTROL packet before advancing
  the buffer pointer by length of payload
* Reject BNEP_EXTENSION_CONTROL packet when the payload size is zero
* Move error logging to more appropriate locations at where the OOB access
  is most likely triggered

Bug: 78286118
Bug: 79164722
Test: Send zero length L2CAP packet to BNEP, send invalid
      BNEP_EXTENSION_CONTROL packet
