Bluetooth: Add support for FCS option to L2CAP
Implement CRC16 check for L2CAP packets. FCS is used by Streaming Mode and
Enhanced Retransmission Mode and is a extra check for the packet content.
Using CRC16 is the default, L2CAP won't use FCS only when both side send
a "No FCS" request.
Initially based on a patch from Nathan Holstein <nathan@lampreynetworks.com>
