Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

If dcid is received for an already-assigned destination CID the spec
requires that both channels to be discarded, but calling l2cap_chan_del
may invalidate the tmp cursor created by list_for_each_entry_safe and
in fact it is the wrong procedure as the chan->dcid may be assigned
previously it really needs to be disconnected.

Calling l2cap_chan_clone directly may still lead to l2cap_chan_del so
instead schedule l2cap_chan_timeout with delay 0 to close the channel
asynchronously.
