biondizzle 3e14a25bb0 fix: don't re-init mbarrier in loop — use phase parity tracking
The mbarrier is initialized once before the loop with count=1.
Inside the loop: issue TMA → arrive.expect_tx → wait(phase) → flip phase.
Re-initializing the mbarrier inside the loop resets the phase, which
breaks the parity tracking and causes the wait to hang.

This matches the CUTLASS/gau-nernst pattern exactly.
