Clear memory in smartlist_remove_keeporder. The smartlist functions take great care to reset unused pointers inside the smartlist memory to NULL. The function smartlist_remove_keeporder does not clear memory in such way when elements have been removed. Therefore call memset after the for-loop that removes elements. If no element is removed, it is effectively a no-op. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

o Minor features (defense in depth):
- In smartlist_remove_keeporder(), set any pointers that become
unused to NULL, in case a bug causes them to be used later. Closes
ticket 30176. Patch from Tobias Stoeckmann.
