struct l2cap_chan cames to create a clear separation between what
properties and data belongs to the L2CAP channel and what belongs to the
socket. By now we just fold the struct sock * in struct l2cap_chan as all
the channel info is struct l2cap_pinfo today.

In the next commits we will see a move of channel stuff to struct
l2cap_chan.

proper timer for hci command timout)

Timer seems to be running when the thing is closed. Removing the timer
unconditionally fixes the problem. And yes, it needs to be fixed
before the HCI_UP check.
