[BugFix][HybridKV] Update the check logic of reinitializing inputbatch (#3540)

### What this PR does / why we need it?
Update the check logic of reinitializing inputbatch, this is a follow-up
pr of #3477. `kernel_block_sizes` is a `list[list[int]]` and the
original logic will always update `InputBatch` when using hybrid blocks,
this pr fixes that
