Caleb Sander Mateos 0d83b8a9f1 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.
