  [RISCV] Don't set AVL if only zeroness is demanded (#74049)

This refactors the logic in transferBefore so that we're moving in the
direction of "keep the existing Info, only change what is needed".

For the sake of review there are two commits in this PR: The former is
needed to make the latter an NFC commit. Neither introduce any test
diffs but the former is not technically NFC, hence why I did not
precommit it.

- [RISCV] Preserve AVL when previous info is ratio only in
transferBefore
- [RISCV] Don't change AVL if only zeroness is demanded. NFC
