A bug in WTinyLFU

[SoftwareDogZ]

In WTinyLFU.c (lines 306-312), the implemented functionality is: when both the window cache and main cache are full and the window_victim from the window cache wins the competition, the main_cache_victim from the main cache should be evicted. However, after completing the eviction, it should set evicted to true to stop further evictions. The statement evicted = true; is currently missing, which may cause multiple objects to be evicted unnecessarily during each replacement.

This is a good catch! Thank you!
Would you mind creating a PR to fix this and evaluating the changes on a few traces to see the impact?
