We cannot call module_put(THIS_MODULE) if this is our last reference. Otherwise,
this call may cleanup our module before it returns.

Gladly, the kthread API provides a simple wrapper for us. So lets use
module_put_and_exit() to avoid a race condition with the module cleanup code.

When all items in the list have the same type there is no much of a point
to use list_for_each except if you want to use the list pointer itself.

Fragmented skbs are only encountered when receiving ERTM or streaming
mode L2CAP data.  BNEP, CMTP, HIDP, and RFCOMM generally use basic
mode, but they need to handle fragments without crashing.

Once the session thread is running, cleanup must be handled
by the session thread only.

Commit fada4ac339 introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by cmtp_del_connection()
which is waiting for the thread to exit -- deadlock.

Revert cmtp_reset_ctr to its original behavior: non-blocking signalling
for the session to terminate.
