Update on "inductor: align inductor behavior with eager mode for spli…

…t_with_sizes"



Fix #99686, for eager mode, if the given sizes is not meet requirements, it will report an error, but inductor can run, I think we need align inductor behavior with eager mode, the behavior will be like after this PR:
