  [VPlan] Remove dead AnyOf reduction case in VPReductionRecipe. NFCI (#130048)

>From what I understand, we only create VPReductionRecipes for in-loop
reductions, and we don't currently support in-loop AnyOf reductions.

We only create VPReductionRecipes in the !PhiR->isInLoop() section of
adjustRecipesForReductions, and this comment from the initial patch
seems to confirm this
https://reviews.llvm.org/D108136#anchor-inline-1038338, so I think we
can remove this check in the condition logic.

I checked compiling SPEC 2017 with -prefer-inloop-predicates and the
added assertion doesn't trigger.
