Fix level zero event synchronization issues for TBX mode

Browse Source 
This change has two issues fixed.
First fix assures event must not download all allocations sent to GPU
when event is not ready.
Second fix performs page walk on event allocation before event allocation
can be downloaded, as download before page walk is not supported scenario
in TBX mode.
