Bluetooth: LE L2CAP: Disconnect if sum of payload sizes exceed SDU
Core 6.0, Vol 3, Part A, 3.4.3:
"... If the sum of the payload sizes for the K-frames exceeds the
specified SDU length, the receiver shall disconnect the channel."
This fixes L2CAP/LE/CFC/BV-27-C (running together with 'l2test -r -P
0x0027 -V le_public').
Fixes: aac23bf63659 ("Bluetooth: Implement LE L2CAP reassembly")
