Fix high traffic PMS lockless methods
The notifyPackageUse method is called so many times that it is
causing a spike in snapshot invalidations. This reverts to a
(broken) S state where the code takes the lock and updates
the time value, but doesn't actually invalidate the snapshot,
preventing the re-generation.
Also fixes a check in grantImplicitAccess that was calling
onChanged() even though nothing changed, which was the other
significant method.
