Subject: [PATCH] eeze/sensor: Fix big memleak that happened on every eeze use.

Really free the list with sensor modules when shutting down. No idea how I
dropped that as I found it in one old local version I had. Thanks to Mike
for the notice and valgrind for the tooling.

Also make sure we don't corrupt the list before we can free it.
