Bluetooth: Initialize new l2cap_chan structure members
Structure members used by ERTM or streaming mode need to be initialized when an ERTM or streaming mode link is configured. Some duplicate code is also eliminated by moving in to the ERTM init function. Signed-off-by: Mat Martineau <mathewm@codeaurora.org> Signed-off-by: Gustavo Padovan <gustavo@padovan.org>
