This patch updates the syntax for nvgpu_arrive Op
in matmulBuilder.py. This fixes the compilation
error for this test.
For the warp-specialized matmul_kernel implementation,
removing the WaitGroupSyncOp (after the mma-main-loop)
fixes the hang observed.
With these two fixes, the test compiles and
executes successfully on an sm90a machine.
