Scan tests failing on blueos

[adayton1]

The fix is adding the following jsrun argument: --smpiargs="-disable_gpu_hooks"

jsrun -n 1 -a 1 -g 1 ./ScanLoopExample
CPU count: 21
CUDA Hook Library: Failed to find symbol mem_find_dreg_entries, ./ScanLoopExample: undefined symbol: __PAMI_Invalidate_region

jsrun -n 1 -a 1 -g 1 ./TestScan
