Parameter validation layer erroneously checks pCommandQueueGroupProperties

I'm seeing some unexpected behavior with the parameter validation layer enabled.

Expected behavior:

Calling zeDeviceGetCommandQueueGroupProperties() populates the memory pointed to by the pCommandQueueGroupProperties parameter.

Actual behavior:

Calling zeDeviceGetCommandQueueGroupProperties() returns ZE_RESULT_ERROR_INVALID_ARGUMENT.

Comments

The issue is that the validation layer expects the ze_command_queue_group_properties_t::stype field to be set by the application. However, it is the responsibility of the zeDeviceGetCommandQueueGroupProperties() function to initialize the data. The work-around is for the application to partially initialize the data by setting all ze_command_queue_group_properties_t::stype fields before calling zeDeviceGetCommandQueueGroupProperties().

I think this is the offending line, and I suspect the solution is just to remove it.

Start at source/layers/validation/parameter_validation/ze_parameter_validation.cpp around line 292 and trace validation for zeDeviceGetCommandQueueGroupProperties(). Reproduce the call with the validation layer enabled, then verify that an application need not preinitialize ze_command_queue_group_properties_t::stype and that the function populates pCommandQueueGroupProperties without returning ZE_RESULT_ERROR_INVALID_ARGUMENT.
