PRCL1 filter not set again - problem fixed in guardian

[Sheila, Jenne, JeffK]

While clearing SDF differences, we caught the same filter-not-on situation that Ansel and Young-Min helped find in alog 31524.  We looked around in the guardian, and Sheila found why they didn't get set, and has fixed the problem.  SDF saves the day!

The problem is that the filters were only being set in the DRMI_Lock_Wait state, so if we gave up on catching the DRMI and went for PRMI, then had a successful transition from PRMI to DRMI without a vertex lockloss, we would never go back to that state, so the filters would never get set.  Sheila has moved the setting of those filters later in the guardian to the offload state that we go through no matter which way we acquire the lock, so this shouldn't be a problem again.
