The identity address update of all channels for an l2cap_conn needs to take the lock for each channel, i.e. it's safest to do this by a separate workqueue callback. Previously this was partially solved by moving the entire SMP key distribution behind a workqueue. However, if we want SMP context locking to be correct and safe we should always use the l2cap_chan lock when accessing it, meaning even smp_distribute_keys needs to take that lock which would once again create a dead lock when updating the identity address. The simplest way to solve this is to have l2cap_conn manage the deferred work which is what this patch does. A subsequent patch will remove the now unnecessary SMP key distribution work struct.
