plugin: Remove special case for plugin stopping while handling hooks

Browse Source 
This used to be necessary because we allocated the `plugin_hook_request` off
of the plugin instance (only tal allocated object we could grab at that
time. Now the plugin was replaced by a list, which itself is tal-allocated,
making that workaround pointless, or even wrong once we have multiple plugins
registering for that hook.
