[f06b69466f8dc5dd55fb42a639c0e4d3f4d83495] OpenCL: Fix USM indirect flags probably caused issues

Manually setting CHIP_USE_INTEL_USM=OFF allows the tests to run to completion successfully.

Skipping clSetKernelExecInfo()
on USM allocations works too (at least for TestLazyModuleInit, TestLargeGlobalVar, TestGlobalVarInit):

It seems that passing anything (valid USM allocations) in CL_KERNEL_EXEC_INFO_USM_PTRS_INTEL lists break kernel launches. A bug in the driver?
