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

[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 brake the guarantee statement in the ObjectMonitor::wait() method and lead to a crash. The missing statement is added.

Tested in tiers 1 - 5.
