Restore control flow on error in EUV

Fix #104649

Since #98574 refactored a piece of scrutinee memory categorization out as a subroutine, there is a subtle change in handling match arms especially when the categorization process faults and bails. In the correct case, it is not supposed to continue to process the arms any more. This PR restores the original control flow in EUV.

I promise to add a compile-fail test to demonstrate that this indeed fixes the issue after coming back from a nap.
