Bluetooth: Lock the L2CAP channel when sending

Browse source

The ERTM and streaming mode transmit queue must only be accessed while
the L2CAP channel lock is held.  Locking the channel before calling
l2cap_chan_send ensures that multiple threads cannot simultaneously
manipulate the queue when sending and receiving concurrently.

L2CAP channel locking had previously moved to the l2cap_chan struct
instead of the associated socket, so some of the old socket locking
can also be removed in this patch.
