  [RISCV] Move unpaired instruction back in RISCVLoadStoreOptimizer (#189912)

There are cases when the `Xqcilsm` vendor extension is enabled that we
are unable to pair non-adjacent load/store instructions. The
`RISCVLoadStoreOptimizer` moves the instruction adjacent to the other
before attempting to pair them but does not move them back when it
fails. This can sometimes prevent the generation of the `Xqcilsm`
load/store multiple instructions. This patch ensures that we move the
unpaired instruction back to it's original location.
