Subject: [PATCH] solaris: Use pool_cache_reclaim, not pool_cache_invalidate.

pool_cache_invalidate invalidates cached objects, but doesn't return
any backing pages to the underlying page allocator.

pool_cache_reclaim does pool_cache_invalidate _and_ reutrns backing
pages to the underlying page alloator, so it is actually useful for
the page daemon to do when trying to free memory.
