Fix the bug in LFUCache#put() method

We should not adopt the scheme of "first put new elements, then judge the capacity, and if it is full, trigger the proceedEviction() method".Instead, we should adopt the scheme of "first determine the capacity, then trigger the proceedEviction() method if it is full, and finally put in new elements".
