[MCA][LSUnit] Fix a potential use after free in the logic that updates memory groups.
Make sure that the `CriticalMemoryInstruction` of a memory group is invalidated
if it references an already executed instruction. This avoids a potential
use-after-free if the critical memory info becomes stale, and the value is
read after the instruction has executed.
