io_uring: introduce io_cache_free() helper
Add a helper function io_cache_free() that returns an allocation to a io_alloc_cache, falling back on kfree() if the io_alloc_cache is full. This is the inverse of io_cache_alloc(), which takes an allocation from an io_alloc_cache and falls back on kmalloc() if the cache is empty. Convert 4 callers to use the helper.
