Subject: [PATCH] homed,shutdown: call valgrind magic after LOOP_GET_STATUS64

valgrind doesn't understand LOOP_GET_STATUS64. We already work around
this in various placed, via VALGRIND_MAKE_MEM_DEFINE(), but we forgot
three places. Let's fix that.

(cherry picked from commit 48f462547d63e1d03bee612e1c77073263e71293)
