Cannot restake to larger duration in native staking

### What version of iotex-core image (or code branch) are you using?
v1.14.0
### What operating system and processor architecture are you using?
macOS m1
### What did you do? If possible, provide a recipe for reproducing the error.
I staked a native bucket for 92 days, and then restake to 79 days at 20 days later
### What did you expect to see?
restake action should success
### What did you see instead?
Error reduce duration before maturity

No file or test is named. Start by reproducing the native staking case on v1.14.0: restake a 92-day bucket to 79 days after 20 days, then trace the validation producing “reduce duration before maturity.” Done means the intended restake succeeds and a regression test covers this duration change.
