MOS search callstack matched BUG 30486436.

INTERNAL PROBLEM DESCRIPTION:
A weak lock may be blocked due to a refuse bast was dropped for incorrect DRM check when refuse bast was issued right after DRM lock replay.

INTERNAL FIX DESCRIPTION:
Add check in refuse bast to handle DRM just replayed the lock. The refuse bast would be valid and should be honored.
