[LV] Don't vectorize first-order recurrence with VF <vscale x 1 x ..>
The assertion added as part of https://github.com/llvm/llvm-project/pull/93395
surfaced cases where first-order recurrences are vectorized with
<vscale x 1 x ..>. If vscale is 1, then we are unable to extract the
penultimate value (second to last lane). Previously this case got
mis-compiled, trying to extract from an invalid lane (-1)

Fixes https://github.com/llvm/llvm-project/issues/97452.
