BUG/MINOR: proxy/stktable: missing frees on proxy cleanup

In 1b8e68e ("MEDIUM: stick-table: Stop handling stick-tables as proxies.")
we forgot to free the table pointer which is now dynamically allocated.

Let's take this opportunity to also fix a missing free in the table itself
(the table expire task wasn't properly destroyed)

This patch depends on:
 - "MINOR: stktable: add sktable_deinit function"

It should be backported in every stable versions.
