tmf: Bug: 499359: Fix deadlock in table when closing trace selection

When closing a trace while a selection range updated signal is handled
in the TmfEventsTable a deadlock can occur because 2 threads are
taking the trace lock and request lock in different order.

The solution is to not use an event request for updating the selection
range in the table.
