Bluetooth: cmtp: Fix deadlock in session deletion
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.
