Add a clearQueueTillFirstFailure interface to DeferredDeleter, which iterates the queue from the front and delete the allocations in the queue till a failure. It is called by defer deletion of allocations occupied by mutliple contexts to unlock the execution in main thread Related-To: NEO-7532 Signed-off-by: HeFan2017 <fan.f.he@intel.com>
