  CAS-13818 : Fix mask cache conflict on tclean restart
  As documented, the fix for the original issue triggered a mask cache
  conflict on restart. In the end the fix turned out to be fairly simple -
  check if the mask exists and is valid, and do not touch it if it is.
  
  So in the first instance, when the mask does not exist, it will do the
  right thing. And it will not try to do anything on the restart either.
  It ended up being a simple inversion of the original logic, with
  appropriate traps in place so it works for both the original bug and the
  derived bug.
