    [NTOS:MM] ExFreePoolWithTag(): Accept tag mismatch, on release build only (#1334)
    
    "Release" builds should not BSoD on 'Freeing pool - invalid tag
specified' case,
    this is compatible with Windows behaviour.
    Nothing changes otherwise concerning the "Debug" builds, where pool-tag
mismatch
    triggers a BSoD as expected.
