 rts: Turn ASSERT in LDV_recordDead into a normal if

 As reported in #15382 the `ASSERT(ctr != NULL)` is currently getting
 routinely
 hit during testsuite runs. While this is certainly a bug I would far
 prefer
 getting a proper error message than a segmentation fault. Consequently I'm
 turning the `ASSERT` into a proper `if` so we get a proper error in non-
 debug
 builds.
