chan_send does restore buffer state in case of an error which is
different than how bt_l2cap_send_cb works as it does always unref in
case of an error.

/* In case of success the ownership of the buffer is transferred to the stack

 * which takes care of releasing it when it completes transmitting to the

 * controller.

 *

 * In case bt_l2cap_send_cb fails the buffer state and ownership are retained

 * so the buffer can be safely pushed back to the queue to be processed later.
