RFR: 8365556: ObjectMonitor::try_lock_or_add_to_entry_list() returns true with the wrong state of the node [v2]

[Anton Artemov]

> Hi, please consider the following change:
> 
> `ObjectMonitor::try_lock_or_add_to_entry_list() `does not change the node state to `TS_RUN `in case of a successful acquisition of the object monitor. In certain cases this can break the guarantee statement in the `ObjectMonitor::wait()` method and lead to a crash. The missing statement is added.
> 
> Tested in tiers 1 - 5.
